Research suggests that spending time with animals can reduce blood pressure. I want to know whether particular animals are better at reducing blood pressure than others. I randomly select 10 participants. Each participants' blood pressure is measured when they enter the lab (Time 1; baseline). Participants' blood pressure is then measured again after they spend a half-hour with a dog. Lastly, participants' blood pressure is measured a third time after they spend a half-hour with a cat. 1. How many levels of the IV are there? A. 3 B. 2 C. 4 D. 1 2. Is the scenario above between- or within-subjects? A. Within-Subjects B. Between-Subjects 3. What test would be used to analyze the scenario above? A. One-Way Repeated Measures ANOVA B. One-Way Between-Subjects ANOVA C. Independent Groups t-test D. Correlated Groups t-test
Contingency Table
A contingency table can be defined as the visual representation of the relationship between two or more categorical variables that can be evaluated and registered. It is a categorical version of the scatterplot, which is used to investigate the linear relationship between two variables. A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.
Binomial Distribution
Binomial is an algebraic expression of the sum or the difference of two terms. Before knowing about binomial distribution, we must know about the binomial theorem.
