Definitions:

Sample Mean

The average value of all the measurements in a sample, calculated by adding all the values and dividing by the number of observations.

Probability Density Function

A function used to compute probabilities for a continuous random variable. The area under the graph of a probability density function over an interval represents probability.

Sampling Distribution

A statistical distribution of all possible samples that can be taken from a given population.

Standard Deviation

A quantification of how much the numbers in a collection diverge from their average, reflecting the spread of data.
