What is the best statistical test to apply when dealing with simple follow-up data (single 2 x 2 table)? ___
a. chi-square test
- fisher exact test
- binomial test
Homework Answers
Answer:
a. Chi-square test
Explanation:
We are given a cross-tabulation 2 X 2 data. We use contingency table for the categorical variables and we know that we use the chi-square test for checking the independence between the categorical variables for the contingency table.

In rabbits, there are many genes that control coat appearance. The EN gene controls whether the rabbits are solid or spotted. The C gene controls whether rabbits tend to be brown or grey. The alleles of these genes follow a simple dominant/recessive pattern. The following test-cross/mapping-cross was set up: spotted and brown...

For the following experiment/question, pick the most appropriate statistical test. You have the following statistical tests as choices: some may be used more than once, others not at all. Assume homogeneity of variance (where applicable) and the validity of parametric tests (where applicable), unless something is directly stated (e.g., “the data are not at all normal”) or otherwise indicated (viz., by the inspection of the data) which would indicate a strong and obvious violation of an assumption. This means you must...
