Hi I was wondering if somebody could help me with these 2 questions:

17) A colleague comes to you with data they have collected for a research project they have been conducting. they have four sets of data recording the weights of rabbits fed with different feed aditives. initially they just wish to know if there is a significant difference between sets of data. you would advise them to:

perform an ANOVA

ask someone else

undertake regression analysis

18) their initial anaylsis shows that there is a significant difference between the sets of data. you therefore suggest they follow up this analysis with:

T-tests

Correlation

a cup of coffee

ANOVA

I do not fully understand, so if possible, if somebody has any spare time to maybe briefly explain aswell.

thanks
