Creating
a New Summary Variable
Using
the New Variable - Summary Function
The
NEW VARIABLE - SUMMARY function, part of the NEW
VARIABLE MENU in EZAnalyze, allows you to create a new
variable that contains a new summary variable (either a total
score or average score - glossary)
quickly and easily - without having to calculate the new scores
manually or by writing a formula to add to your Excel data
sheet. In addition to the examples provided here,
another example of how you can summarize data with a new summary
variable is for creating a total score for a survey you have
created. If the survey has 10 items, you can create a new summary
variable that contains either the average (mean) score or the
total (all scores are added together) score for the survey.
To
create a new summary variable for your data, select the "New
Variable " option from the EZAnalyze menu in Excel, then
select "Summary
Variable."
In
the "New Summary Variable" dialogue box, select
more than one variable from the variable list. In the example provided above, you
would select all 10 variables representing each question in
your survey (hold down the CTRL key to select more than one
variable) from the variable list.
Next,
select a method for summarizing your data. If you select "Total," all
of the variables you selected will be added together, and the
result displayed as a new variable. If you select "Average," the
average (or mean) score will be the result displayed as a new
variable.
Next,
give your new variable a name in the "Variable Name" box.
This new name should be a variable name that has not already
been used.
When
you click OK, a new column will be added to your data sheet
that has the name you provided in the "Variable Name" box.
The values contained in the cells of the new column will be
from the summary function you have chosen.
