Answer:

The Key difference between average vs weighted average is that simple average is nothing but simply adding up all the observation values and dividing the same by the total number of observations to calculate the average whereas weighted average is an average where each observation value will have a frequency assigned.

The weighted average involve the frequency of scores while the non-weighted average do not include the frequency of scores.

To calculate a  non-weighted  average such as a mean average, all we need to do is to sum up the scores and divide this sum by the number of scores. For a weighted average, each score must have a frequency attached to it. This frequency is called specific weight.

While the non-weighted  average such as a mean average is a measure of central tendency, the weighted average tends to be biased towards the scores that have the largest frequency.
