A small university town has four local food restaurants that make deliveries. A group of marketing students were assigned to do a research project for their class assignment to compare how promptly the four restaurants deliver. On randomly chosen days, they order a chicken rice set from each restaurant, then record the elapsed time until the chicken rice set delivered to their college. Assume that their college is approximately the same distance from the four restaurants. The data are analysed using SPSS and the results are illustrated in Table 2a and
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.
