Welcome to the Community.

It appears that you only have a single measurement for each of the groupings specified in Column 1. The various Means tests available under the Compare Means require raw data as input.

just looking at your figure...

It is very likely that you have Cleaved vs. something else, and for those two categories you have 6 replicate measurements for each (treated 1-6).

Your data should be formatted with at least three columns. Column 1 will have Cleaved and the other category, Column 2 will have the replicate measurements (treated 1-6), and Column 3 will have your measurement data.

Right now you have a column with lables like, "Cleaved, Treated 1". This column has two pieces of information in it that need to be split.

Use Cols>Utilities>Text to Columns, and specify a comma as the delimiter. This will give you two columns that you need.

With the data in this format, put Data in the Y role, and Column 1 in the X role. Then you will see the t-test option.

-The t-test options only show up in the red triangle menu when there are only two groups of data.

-ANOVA is an acronym for Analysis of Variance. When there is only one measurement per group, there is no variance.

I hope this helps
