WebWhen can the chi-square goodness of fit test be used? When: a. We conduct a multinomial experiment. b. We perform a hypothesis test to determine if a population has a normal distribution. c. We perform a hypothesis test to determine if two population variances significantly differ from each other. d. We conduct a binomial experiment. WebFirst we will calculate the observed proportions and then copy those results into a matrix format for plotting. We’ll call this matrix Matriz . See the “Chi-square Test of Independence” section for a few notes on creating matrices. The second example uses the package ggplot2, and uses a data frame instead of a matrix.
