A popular myth is that for identical twins, one is the "nice one" and one is the "mean one." Fourteen pairs of identical twins were randomly selected and given a personality test for measuring "niceness" or “meanness" where the higher score implies "niceness" and a lower score implies “meanness." At the 1% significance level, is there a difference in the personality scores between the identical twins. First Born 43 54 49 53 49 52 58 51 59 48 45 49 47 46 Score Second 52 47 46 50 51 50 45 46 47 49 54 50 54 Born Score 50

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.
