What are the effects of training group (blue, red or yellow group) and gender on work performance scores?

Iv, dv, covariate, and best method of analysis questions

The effects of training group and gender on work performance scores can vary significantly depending on the context. For example, if a study was conducted to measure the effect of different colors of safety vests (blue, red, or yellow) on construction workers’ performance, it is likely that all three groups would show similar results. However, if the study was conducted to measure differences in math test scores between male and female students split into blue, red or yellow groups then gender may have a greater impact on results.
