2.3: Data transformations
2.3.1 Data transformations (detailed contents)
Summarises full details of the coverage and contents of each of the entries below.
Selecting variables for analysis, changing the names of variables, changing the values of variables. Creating new variables from existing ones. Selecting cases for analysis as a transition from analysing one variable to analysing two or more variables.
2.3.1.1 Data transformations (Tutorial introduction)
2.3.1.2 Exercise to rename variables (this is for the 1989 BSA data: a new one is being prepared for 1986)
2.3.1.3 Conditional frequencies exercise
2.3.1.4 Specimen answers for exercise 2.3.1.3 (Conditional frequencies)
This is the final draft of a very extended and detailed exercise: it's quite long (26 pp) but manageable. It uses data from the 1986 British Social Attitudes survey as an exemplar as preparation for moving from
analysing one variable to analysing two or more variables.
The following are in preparation
2.3.1.5 Conditional frequencies homework
repeating exercise 2.3.1.3 on the same variables from the 1989 British Social Attitudes survey.
2.3.1.6.ff Specimen answers for conditional frequencies homework
