Data: |
Any data that you want to save to use in your
analyses. |
Field: |
The data also types are kept in the
same field. Ex: Name, First name, Size, Salary, Quantity... With Excel,
the data of the same field are kept in the same column. The names
of fields are always in the first row of a Data list. |
Record: |
All the data concerning a person, a thing
or an event. With, Excel, every row of the data list is a record.
So, a data list can contain records on things, persons or events. |
You can rewrite the data below in a worksheet or use this datalist.xls file.
You can also find other files on the demonstration files Web page.

Here is a data list from employees of a company.
As for the previous picture, the first row of a data list always contains
the name of fields. Every following row contains a record that describes a
person, a thing or an event according to the fields that you chose. A list of
data should never have of empty rows. That is that all the records should follow
itself continuously.
Sort the data
Excel allows you to sort out quickly the contents of a data list to help you to find quickly what you look for, to put of the order and to organize the
data.
You can use buttons on
the toolbar to sort out a column in increasing or lessening order. All the records
of the data list will move according to the order that you chose.
It's however necessary to pay attention not to make a block and then to sort
out. Otherwise, only the data and not record will be sorted out. It will have
the effect of mixing the data. Not recommended.
Excel offers you another way more advanced to sort out the data list.
The next exercise consists in sorting out the records according to the name
and the First name.
Place
the cursor on any cell of the data list.
From
the Data menu, select the Sort option.

You can sort out up to three fields at the same time in increasing or lessening
order.
For
the first sorting, select the Name field.
Sort
in ascending order.
For
the second sort field, select the First name field.
Sort
in ascending order.
The sorting of the first box will have the priority on the second
sorting. It means that Excel is first going to sort out on the
name. For the records with the same name, Excel will sort out
these records according to their First names.
Press
the Options button.

This is just for demonstrating you that you can sort out according to the normal
order or according to the list that you prepared in advance.
Press the Cancel button.
To
carry out the sorting, press the OK button.

The data list is now sorted out according to the chosen criteria. You can
carry out a sorting up to three fields at the same time.
Filters
It can be frustrating to try to find data you need in a long data list.
The automatic filter is an option to help you to find quickly the wished data.
The automatic filter
Place
the cursor on any cell of the data list.
From
the Data menu, select the options Filter and AutoFilter.

In the first row of the data list, there are now boxes of selection having
the name of fields. By clicking the button in the right-hand side of the name
of the field, you can limit what's shown in the list in what you need.

From the box of selection of the Name field, select Bibeau.

As you can notice, there's only two records, or persons in this case, who answers
to the filter. It's always possible to combine filters to limit even
more the results.
From the box of selection of the Titles field, select the Manager option.

From
the Data menu, select the options Filter and Show All.
OR
From the filter boxes on the fields Name and Title, select the All option.
You can do more with AutoFilter. You can filter a
field on two conditions.
Place
the cursor wherever on the column of the Name field.

From
the filter box for the field Name, select the Custom option.

A new window opens offering you to place until two conditions. Furthermore,
you can choose among several conditions the one that answers better your needs.
For
the first box, select the condition equals.
For
the second box, select the name Albright.
Between
both conditions, select the Or option.
For
the third box, select the condition equals.
For
the fourth box, select the name Jenkins.
To
filter according to these conditions, press the OK button.

The automatic filter allows you to realize interesting searches.
But the advanced filter offers you some more of possibilities and flexibilities.
From
the Data menu, select the options Filter and Show All .
OR
From the filter box on the Name field, (All) select the option.
The advanced filter
Excel allows you also to carry out more complex searches. You can choose the
fields of your choice as the criteria and enter values. You can also use the
conditions AND and OR under the format of a wire netting.
Before using an advanced filter, you need at least two things: a list of
data and a area of criterion.

Add
the following data in the appropriate cells.
The first row of the criteria area should contain the name of the fields
that you need for the criteria. For this exercise, it's about fields Title
and Category. pay attention to the spelling! If the name is not identical in
the name of the field of the data list, Excel will not show you the result
that you want.
The following rows include the criteria. By default, Excel presumes the sign
=. For the example, Title = Adminitrateur. You can also use the other ways
to estimate such as >, <, <=>, =, <. To apply the conditions AND and OR, you should use the wire netting of Excel. The criteria
that are on the same row use the criterion AND. In the example, the
third row of the area of criterion s to Title = Worker AND Category
= 4. The criteria that are on different rows use the condition OR.
It allows to have the result of several conditions at the same time. For this
exercise, all the criteria s to Title = Administrator OR Title
= Worker AND Category = 4.
Place
the cursor on one of the cells of the data list.
Otherwise, Excel will not want to carry out the filter.
From
the Data menu, select the options Filter and Advanced Filter.

The advanced filter allows you two actions: filter the list or copy the
data in another place. For the next stage, let the action filter. The following
exercise will consist in using the copied action. Normally, Excel should have
correctly chosen the good beach of cells for the data list. But, it's always
necessary to verify. Contents in cells around the data list are not needed.
It's as well necessary to make sure as Excel correctly chose the good criteria area. Otherwise...
Click
in the Criteria range box.
Select a range of cells with the necessary cells for the criteria area. For the purpose of this
exercise, select cells between I1 and J3.
Press the Enter key.
It's not necessary to take more cells than it's necessary for the criteria area. Otherwise, the result will not be what you expect.
Because
there are the other actions to be carried out, press the OK button.

An advanced filter gives you more options than an automatic filter.
From
the Data menu, select the options Filter and Show All.
The advanced filter offers also another interesting option. Instead of masking
the records that don't answer the criteria, the filter can copy "checks"
records in another place on the worksheet. The next exercise consists
in using the filter advanced with the option to copy the records.

Add
the following data in the appropriate cells.
The first row of the destination of the advanced filter should contain the
name of fields, correctly spelt, the result of that you want to see. Cells
below these should be free. It's in those that the records that answer the
criteria will be copied.
Place
the cursor on one of the cells of the data list.
From
the Data menu, select the options Filter and Advanced Filter.

From
the list of the possible actions, select Copy to another location option.
The beach of the data list and the criteria area should be correct. But
it's always necessary to verify. It remains to determine the destination.
Place
the cursor in the Destination box.
Select
cells with the names of the fields the result of that you want to see. For
this exercise, select cells between I6 and K6.
Press the Enter key.
Activate
the Unique records only option.
This last option avoids having the same record several times in the result if it
answers several criteria that you entered.
Press the OK button.

Note:
Enlarge the salaries column if you see the "#" symbol.
Excel copies the records in the place for that you asked.
The data form
Instead of entering, changeing and removing the data directly in the cells
of a worksheet, Excel allows you to manage your lists of data by using a data
menu. The next part consists in demonstrating you the functioning of this grid.
Place
the cursor on one of the cells of the data list.
From
the Data menu, select the Form option.

Excel offers you now the possibility of changeing the data of each of the records
from this small form. Here is a short description of buttons.
New |
Add a record to the data list. This record
will be placed at the end by the list. |
Delete |
Delete a record of the data list. Excel will
ask to confirm before proceeding. |
Restore |
Allows to restore the values of a record before
the modifications that you brought. Should be used before changing record. |
Find Previous |
Pass in the previous record. |
Find Next |
Pass in the next record. |
Criteria |
Allows to establish research criteria and only
to show the required records. |
Close |
Close the menu to return to the worksheet. |
The next exercises consist in putting into practice this menu.
Press
the Find Next button.
The next record appears in the boxes of the left of the window. You
can change their contents your choice. However, you can not change the contents
of the field Category because it's about a formula.
By
using the Previous and Next buttons, move through the records to change
Josée Dupuis's salary from 22 500 $ to 24 500 $.
It's with regret that we learn that Mr. Paul Carter is leaving the company.
Mr. John Savage was hired to replace him. Here are the relevant
data to be added to the data list.
NAS: |
211211001 |
NAME: |
Savage |
FIRST NAME: |
John |
SEX: |
M |
TITLE: |
Worker |
SALARY: |
22 000 $ |
Place
the cursor on one of the cells of the data list.
From
the Data menu, select the Form option.
To accelerate the query, the option of the criteria will be used
to look more quickly for the popular record.
Press
the Criteria button.

Enter
the text: Cardinal in the NAME box.
Press
the Find Next button.
The record of Paul Cardinal will appear on the grid. It's now necessary to remove it from the data list.
Press
the Delete button.

Excel asks you to confirm the deletion of the record.
Press the OK button.
It's now necessary to add the new employee.
Press
the New button.

Enter
the data in the appropriate cells.
Press the Enter key.
Press
the Close button.

Mr Cardinal is not any more in the list and Mr Sauvageau was added to the end
of the data list. As you notice it, it's easier to manage the data by using
the bars that by looking on the worksheet.
The database functions
When you understood the lists of data and the areas of criteria, you can then
carry out analyses with the available functions of Excel. There is 13 in everything.
Here is a short description of some of these functions.
=DSUM (data list area; number of the
column to add; criteria area) |
Show the total of a certain numeric field according
to the wanted criteria. |
=DAVERAGE (data list area; number of
the column to average; criteria area) |
Show the average of a certain numeric field
according to the wanted criteria. |
=DMAX (data list area; number of the
column to find the highest value; criteria area) |
Show the biggest value of a certain numeric
field according to the wanted criteria. |
=DMIN (data list area; number of the
column to find the lowest value; criteria area) |
Show the smallest value of a certain numeric
field according to the wanted criteria. |
=DCOUNT (data list area; number of the
column to find the number of records that anwsers the criteria; criteria
area) |
Show the number of records that answer the
wanted criteria. |
The next exercise consists in you demonstrating
how to use these functions with =dbsum(). It's a question of knowing that's
the total payroll of the administrators and the workers of category 4. The
data list, A1 to G16, and the criteria area, I1 to J3,
was already established in the previous exercises.
To use the function =dbsum(), and most of the others, you need three data or
parameters: the area of the data list, the name of the field to be added
and the area of the criteria area. Here is how to write it by using the assistant
of the functions.
Place
the cursor in the I4 cell.
From
the toolbar, press the button .
OR
From
the Insert menu, select the Function option.

The first column describes the categories of functions covered by Excel. The
second column contains the list of the functions that you can use.
From
the list of the categories of functions, select the Database option.
From
the list of the functions, select DSUM.
Press
the OK button.

A new window appears asking you for the three parameters mentioned before.
At the foot of this one, there is a description of the elements that you should
enter each of the boxes. The first box is for the data list.
Click
in the Database box.
OR
Press
the button in the right-hand side of the Data base box.
Select
the A1 to G16 cells.
Press
the Enter key or the button at the end of the box as the box may be.
The cursor returns to the window of description of the function =databaseSum
().

Click
on the Field box.
Notice that the description at the foot of the window looks now of the data
for second box. You can also press the button to fetch the required data.
Click
in the F1 cell.
Press
the Enter key.
For the name of the field, you can enter the name of the field between quotation
marks ("salary") or to enter the number of the column. Because the field salary
is the sixth column of the data list, you can also enter the number
6.

All the required data entered. You have even the result at the foot of the
window.
Press the OK button.
The result is 185 000 $. If you look at the contents of the bar of formula,
you'll see that the formula looks like in =dsum(A1:G16; F1; I1:J3).
It would work as well under this format =dsum(A1:G16; 6; I1:J3) or =dsum(A1:G16;
"salary"; I1:J3). There are several ways to describe the field to be added.
try now with the other functions of the category.
Analysis on groups
The functions of analyses can take out you interesting data. However, it can
take time if you want the same data for several groups of data. For example,
you need several functions to know the payroll by category of employees.
Excel offers you the possibility of showing quickly subtotals of several
functions (sum, averages...) by group.
Before even beginning analyses, it's first necessary to sort
out the records on the field the subtotals of that you want to see. For this
exercise, you must sort out on the field Category.
Category places the cursor on one of the records under the field.
By
using buttons ,
to sort out in increasing order the field Category.

Here is what should look like data list if you completed all the operations
of this Web page. It's now the time to see the total of salaries by category.
Place
the cursor on a cell of the data list.
From
the Data menu, select the option Sub-totals.

From the first box, Category selects the field.
For
the second box, select that you want the Sum function.
From the third box, select that you want the sum the Salary field.
The window of the subtotals offers you also the possibility of replacing the
total under of previous analyses. You can also accumulate these analyses to have
more data. For example, you can have the sum and the average at the same time
on the worksheet. It's necessary to pay attention to the function
NBVal that's supposed to give the number of record by group. However, it
does not seem to want to work correctly with the other functions.
You can also ask to have a page break after every group. This is interesting
if you think of printing the results. You can also have at the end of the list
of data a synthesis of the functions for that you asked.
Press the OK button.

The options to the left of the worksheet allow you to mask (-) and of
rafficher (+) the categories. You can then concentrate the elements that
you consider important. Buttons 1, 2 and 3 allow to mask and to show the synthesis,
the subtotals and the records. Press these buttons to see their effects.
To return to the initial presentation:
Place
the cursor on a cell of the data list.
From
the Data menu, select the Sub-totals option.
Press
the Delete all button.
The list reappears without the sums of the categories. You can now push your
analyses a little farther thanks to the data list and the options. |
