turkey HSD test from DOE

Created: Aug 25, 2022 11:08 PM  |  Last Modified: Jun 8, 2023 05:11 PM (502 views)

Hi,

I am currently working on 2^3 design of experiment. After Anova, when I am going further for turkey HSD test for each level of factor interaction,the test is not giving me level interaction properly. double level interaction it is giving. eg. Price (low, high) Quality(ok,good). turkey HSD should give price (low).quality(ok) results. But it is giving price(low,high) quality(ok,good) results. which I am able to interpret. Please help am I wrong somewhere or not able to interpret?please guide.

First of all, the name of the procedure is Tukey HSD, not turkey HSD. It is named after its creator, John Tukey.

The test reports pair-wise comparison of all 2x2=4 pairs. What do you mean by "the test is not giving me level interaction properly?" What do you expect to see?
