ANOVA Help

#1
Hello everyone!

I am learning how to use SPSS for one of my classes and my professor does not explain things very well. She wants us to run a one-way ANOVA with a post hoc Tukey test. She provided data for us to use, but for some reason warning messages populate for the Tukey test. It says that the test cannot be performed because at least one group has fewer than two cases. Any ideas on how to fix this? This is the only problem on my homework that I have been having issues with and my professor is no help. I appreciate any and all help with this!

I used SPSS a long time ago.. but it seems you got the error message.
Not sure I'm helpful, but it seems you enter one group with less than 2 values? how many values do you have in each group?

There are 5 columns of data. 3 of the 5 have 10 values, one has 9 values, and one has 8

For a oneway analysis of variance in SPSS, all values of the dependent variable
are in the same column. In another column, the group membership of each
subject. Did you provide this?

With kind regards
