1. A teacher wants to find out if it is true that students who are good in math are not that good in English so he gathered a data consisting of 15 students with the following grades in Math and English. Using the data gathered by the teacher, is it safe to say that students who are good in Math are more likely to be poor in English? 5 Student number 1 2 4 6 7 8 10 11 12 13 14 15 Math Grade 90 92 93 93 88 85 90 90 92 93 95 96 93 83 96 English Grade 91 92 94 90 89 87 91 92 91 91 94 93 94 85 92

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.
