There are 4 TV sets at the student center of a large university lounge. At a particular time of each day, four different soap operas (namely 1, 2, 3 and 4) are being transmitted at these TV sets. The attending number of students viewing the 4 soap operas are 80, 88, 79 and 53. The percentage of audience captured by these shows during one semester after the summer break are 25%, 30%, 25% and 20%, respectively. The survey consists of 300 students. a) if the viewing pattern has not cha
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.
