1. Conduct both these types of ANOVA (independent and rm) with the dataset below.

NC group	HC group	HC-LNP group
15.0	60.625	44.375
5.625	29.375	18.75
-9.375	25.0	8.125
-10.625	20.0	-1.875
-25.0	25.625	-16.875

2. How do the results differ between tests? What do the different MS, SS, and df values mean?

3. Practice conducting a two-way ANOVA (independent and rm) using the following dataset of fasting insulin concentration (pmol/ml) in obese and non-obese pre-diabetic patients after receiving a regular oral placebo or the anti-diabetic drug metformin for one week.

Obese placebo	Non-obese placebo	Obese metformin	Non-obese metformin
0.176	0.117	0.127	0.089
0.170	0.123	0.122	0.091
0.182	0.120	0.121	0.091
0.181	0.117	0.117	0.091
0.180	0.117	0.119	0.092

4. How do the results differ between tests? What do the different MS, SS, and df values mean?

5. When are Bartlett's and Levene's tests more appropriate? How do you proceed if the results are significant?
