Post-Hoc Tests for One-Way ANOVA

[KimJonghrill]

These videos have helped me so much. I'm doing undergraduate research where I'm ranking the discriminatory power of measurement features in an image analysis program. I'm comparing biofilm architectures of five treatments at two spatial scales (1x and 10x resolution). We've been using ANOVA, Tukey, and Mann Whitney tests to compare the 1x to the 10x images for each treatment. Before watching these videos I had no idea what the significance of these tests were, or really why I was doing them.

Would you provide a video on how to perform the ANOVA post-hoc tests on SPSS?

[melissahanzlick]

we worked this out with my class and we came of with an answer of 7.53 SSbetween instead of 7.14 for the post hoc test of scheffe at time stamp 4:51 of the video. how did you arrive and the answer of 7.14?

How to Calculate the p value in the newmaN keuls test??

If we are comparing how different they are then that means they can be dependent variables right then it is almost same like repeated measures anova

Why do you choose the number 3 as the "degree of freedom between" when using the q table at 3.21 (time stamp), when it was calculated as 2 in the "one way ANOVA" vedio ?

Why would you use MS-within instead of MS between groups?

[jumanaraggam]

can the results in the post hoc test be negative?
i tried the scheffe method on other questions but the results were less than the F I got originally. What does that mean?

[Bananzaman]

Isn't the MSbetween equation the SSbetween, and then divided by df?
