The following is the number of sales per day for Kim Ryan, a courteous salesperson who worked for four days before being laid off: 1, 11, 9, 3. Suppose samples of size 2 are randomly selected, with replacement, of this population of four values. List the 16 different possible samples and find the mean of each, then identify the probability of each sample.
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.
