What do you mean by compare? Do you mean to test the hypothesis that there are no differences between groups, between group 1 and all other groups or something else?

Hi to all,

I have question about average values. I have data that looks like this:

V1 V2 V3 V4

1

3

5

3

3

1

3

4

5

4

5

1

4

4

5

4

2

2

2

These are answers on scale from 1-agree to 5-disagree to certain question. Variables V1, V2, V3, V4 are basically different groups of respondents but all answers are to the same question. It is the same as this one:

Q G

1 1

3 1

5 1

3 1

3 1

1 2

3 2

4 2

5 2

4 2

5 3

1 3

4 3

4 3

5 4

4 4

2 4

2 4

2 4

Q stands for question and G stands for Group.

So now I need to compare means in following way: Group1 vs. average of all other groups. How should I calculate the average of all other groups? Is it simple as making them all Group2 or should I pay attention to some other details?

Hope I wrote it clear enough:)

Samir
