# Challenge: Least Significant Difference and Mean in R

Use what you’ve learned so far to complete the following challenge.

## We'll cover the following

## The least significant difference

The least significant difference (LSD) test is used in the context of the analysis of variance when the F-ratio suggests rejection of the null hypothesis $H_0$. In other words, when the difference between the population means is significant. This test helps us identify the populations that have statistically different means.

## Problem statement

You’re given a piece of R code to calculate the least significant difference (LSD) for the Darwin’s maize dataset. Your task is to compute the LSD with its mean and plot it.
