Question

Consider the following data: 6, 8, 2, 3, 4, 4, 5, 5, 9, 6, 6, 7,
7 ,7, 7, 8, 8, 8, 8, 9, 9.

What type of distribution is this?

Answer #1

Frequency bar plot below

Box plot below

More or less based upon both the graphs we can say that the distribution is negatively skewed and hence we can say that the distribution is negatively skewed normal distribution

(Graphs plotted in R. R code below to plot the same)
