Inference for Categorical Data in R
Exercise instructions
- Using
gss2016
,construct a bar plot of proportions capturing the relationship betweenregion
andhappy
. Plots like this are easier to read when the variable with the fewer number of levels is mapped tofill
. - Use
chisq_stat()
to compute the observed chi-squared statistic associated with this bar plot and save it aschi_obs
.
