What is Mean?
The mean is the straightforward meaning of the normal of a lot of numbers. In measurements, one of the markers of focal propensity is the mean. The normal is alluded to as the number-crunching mean. It's the proportion of the number of genuine perceptions to the absolute number of perceptions.
The weighted mean is given as,
Average = [Σ(wx)] / x
Coordinate 2 has a weight of 2, coordinate 5 has a weight of 1, and coordinate 7 has a weight of 3.
Then the weighted average of the given data will be
Average = [2 × 2 + 5 × 1 + 7 × 3] / [2 + 5 + 7]
Average = (4 + 5 + 21) / (14)
Average = 30 / 14
Average = 2.14
