what is the mean of these numbers 15 24 16 18 21
You asked:
Find the arithmetic mean of the following data: \(15, 24, 16, 18, 21\)
MathBot Answer:
The arithmetic mean (often referred to as the average, arithmetic average, or the mean) is a value indicating the typical value of the elements in a given data set. It is computed by summing the numbers in a data set and dividing that number by the amount of numbers in the set.\[\overline{x} = \frac{1}{n}\sum_{i=1}^{n}{x_i}\] where \(x_i\) represents the individual values and \(n\) represents the number of values in the data set.
The arithmetic mean of \(15, 24, 16, 18, 21\) is \(\frac{94}{5} = 18.8\).
