Solution
The best type of plot for checking if your data is normally distributed is a. ggqqplot() from the ggpubr library.
Here's why:
A Quantile-Quantile plot, or Q-Q plot, is a graphical tool to help us assess if a dataset follows a particular theoretical distribution. It compares two probability distributions by plotting their quantiles against each other. If the two distributions being compared are similar, the points in the Q-Q plot will approximately lie on the line y = x. If the distributions are linearly related, the points in the Q-Q plot will approximately lie on a line, but not necessarily on the line y = x.
Therefore, if we want to know if our data is normally distributed, we can use a Q-Q plot to compare our data's distribution with a normal distribution. If the points lie approximately on the line y = x, we can assume that our data is normally distributed.
The ggqqplot() function from the ggpubr library in R allows us to create Q-Q plots easily.
