An investor bought shares in the five firms whose stocks were the five best Dow Jones companies in the first quarter of the year. In the second quarter, however, the performance of these five firms was rather ordinary. The statistical phenomenon taking place here is A. The law of averages says that these stocks must perform at the market average over the long haul. B. The Central Limit theorem says that distributions tend to normal, so that the abnormal results of the previous quarter are difficult to repeat. C. Statistical independence indicates that performance in the first quarter cannot be used to predict performance in the second quarter. D. The regression effect says that high performances tend to return to average.

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.
