Problem description:

I have the same problem as the following brother: reposting.

The graduation thesis got this result:

20 litters of mice of the same age and variety were randomly divided into 4 treatments, each with 5 litters. Treatment control group, treatment group fed with 50ppm A drug, treatment group fed with 60ppmB drug and treatment group fed with 50ppm A+60ppm B at the same time. Finally, the weight gain data of each litter of mice are obtained.

How to discuss whether drug A and drug B have synergistic effect on weight gain in mice in SPSS? Thank you.

Analysis:

Factor analysis should be used to set three variables.

A. whether to use drug a, grade 2, 50ppm.

B. whether to use drug b, grade 2, 60ppm.

C. the response variable is weight gain.

Analysis process:

Analysis-> General linear model->; Univalent

Dependency list: c

Fixed factors: a and b

Run.

If Sig. Results the p value of a*b was less than 0.05, which had synergistic effect.
