50 psychology students took a standardized test. The scores are summarized in the GFDT below. Scores Frequency 160 - 179 6 180 - 199 11 200 - 219 12 220 - 239 10 240 - 259 11 You would like to build a relative frequency distribution for this data set to easily compare it to another class of students.What is the relative fequency for the fourth class, 220 - 239?Enter answer as a percent (but do not include the percent symbol).relative frequency = _%
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.
