Extract of sample "ANOVA: One-Way Analysis of Variance"

Assignment 3 (Part 3) – Statistical Analysis of Data – ANOVA (One Way Analysis of Variance) A. Research Question: Is there a difference in the % water content between the groups of kidney exposed to varying times of ischemia? B. Null Hypothesis: There is no difference in the % water content between the group of kidneys exposed to varying times of ischemia. In other words, there is no effect of varying times of ischemia on % content of water in the group of kidneys. In symbolic form, H0: µ1 = µ2 = µ3 = µ4 (all the means are equal) (1-Control, 2-30 min ischemia, 3-60-min ischemia, 4-120 min ischemia) The alternate hypothesis will be H1: Not all the means are equal (at least one mean is different) C.
