How to get descriptive statistics on questionnaire items by group using SPSS?
I have carried out an evaluation of a product using likert scale questionnaire and imported the date into SPSS. I have my columns arranged as follows:
ID, Group, Q1, Q2, Q3, Q4
I have two different groups completing the questionnaire, with each person a different numerical ID. Under the Q columns, I have the score given for that person (from 1-5) from the Likert Scale.
In all there are over 300 responses.
I am running analysis using 'descriptive statistics/frequencies' from the menubar and not getting the tables I am looking for. Basically, it is including all respondents together, whereas I would like it to compare the two groups in the tables.
How can I get descriptive statistics on questionnaire items by group using SPSS?
In addition, if you have any further tips as to what analysis I could perform on this type of data in SPSS I'd be most grateful. I'd like to show that there isn't a significant difference in opinions between the groups, and from looking at the data, it appears that this is the case.
Answer
One option
- split file by group
- run descriptive statistics as usual
