A psychologist recruits 30 students to participate in an experiment. The plan is to randomly divide the students into groups to be given one of three versions of a memory test. Half the students will be given a quiet environment to take the test, and half a distracting environment. That is, the plan is to have five students in each Test/Distraction combination. However, two students misunderstand the instructions and their data has to be discarded.
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.
