This data set refers to a fictitious study that involves testing the impact of two different types of interventions in helping students cope with their anxiety concerning a forthcoming statistics course.

Students were divided into two equal groups and asked to complete a number of scales Time 1. One group Group 1 was given a number of sessions designed to improve mathematical skills, the second group Group 2 was subjected to a program designed to build confidence in the ability to cope with statistics. After the program Time 2 they were again asked to complete the same scales that they completed before the program.

They were also followed up three months later Time 3. Their performance on a statistics exam was also measured. This file contains data extracted from hospital records which allows you to try using some of the SPSS data manipulation procedures covered in Chapter 8 Manipulating the data.

If any of these variables had contained data after a decimal point e. This might fool you into thinking that there was a problem with reading in the data, when actually there is a problem in displaying the data.

If we assume that mpg had two decimal places, we could tell SPSS to display mpg with two decimal places with the formats command. If you read fixed column data with variables with data after the decimal, be sure to use the formats command or an equivalent to make sure that the places after the decimal point will be displayed.
