Hi Within the ANOVA (one-way) function, use the "comparisons" tab where you can select the Dunnet test (among others) to undertake multiple comparisons.

Nouran Atef

I put the results of my control and other groups in separate columns, then I do like what you said, but whenever I choose Dunnet test, an entry called " control level" is required and I don't know what it means..

It is just asking you to enter the column that contains the results of the control group

Loyal Hall

Might be a little late for you, but in "Terms" you identify which column contains the treatments. And in "Control levels" you need to type the label of the control group in quotes.
