- A climatologist is interested in comparing the frequency of cloud cover in Thunder Bay and Sudbury. Data is collected from 500 days chosen at random from Thunder Bay and 500 more from Sudbury, each indicating whether or not there was significant cloud cover on that day in that city. What is the best statistical method/test to determine if Thunder Bay and Sudbury have the same frequency of significant cloud cover? Regression Pooled Variance Estimate Two-Sample t test Difference in Proportions Chi SquareIf I have a study where I am testing the relationship between abundances of zebras and gazelles, what kind of parametric statistical test would I use? Correlation Regression ANCOVA O ANOVAANOVA Involves "decomposition of variance-a fancy term that means we examine diferent sources of variabilty. Name and describe each of the sources of varlability used in an ANOVA and tell me which source of variability we always want to be largest and why.
