For questions e and f, name the single most appropriate statistical approach, from among the statistical tests you were taught in this course.

e. You want to test for an association between two numerical variables: how long it takes rats to enter a dark box, and how aggressive they are towards other rats.

f. You want to test whether there is an association between hair color (brown, blond, black, or red) and eye color (blue, brown, green, or other) in humans.

Answer #1

(e)

The name of the single most appropriate statistical approach:

Correlation and Regression Analysis

Explanation:
Correlation gives the strength and direction of relation between two numerical variables Here: how long it takes rats to enter a dark box, and how aggressive they are towards other rats. : Regression Analysis gives the linear relation between two numerical variables:

(b)

Chi Square Test for association (Contingency)

Explanation:

Chi Square Test for association (Contingency) is used to measure the association between two categorical variables: Here: hair color (brown, blond, black, or red) and eye color (blue, brown, green, or other) in humans.

PLEASE Include Explanation Read the scenario and pick the most appropriate nonparametric statistical test (assume several assumptions of parametric tests were violated). Imagine that marketing researchers working for a food company want to determine whether children would prefer ketchup of a different color. They develop green and blue to compare to their standard red (all taste the same). They have children taste all three colors of ketchups (a correlated-groups design) and rank each on a scale of 1 – 10....

For the following experiments/questions, 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...
