Question: Write the mean formula and explain its terms?
Sure! The mean, also known as the arithmetic mean or average, is a measure of central tendency that represents the typical value of a set of numbers. The formula for calculating the mean of a set of n numbers is:
�
ˉ

∑

�
xˉ=n∑i=1nxi
In this formula, x_i represents each individual number in the set, n represents the total number of numbers in the set, and Σ represents the summation symbol, which means to add up all the values. The mean is calculated by adding up all the numbers in the set and then dividing by the total number of numbers in the set.
