Central Limit Theorem
It states that the average of the sample means will be equal to the population mean.
Irrespective of how the population data points are distributed, the plot of sample means will always look like a normal distribution.
For a normal distribution, we know that,
Mean, Median and Mode are equal
Data is symmetric about the mean
Using these properties we can draw inferences about the population as a whole.
