find the mean 1, 1, 1, 1, 2, 2, 3, 3, 4, 4, 4, 4, 5, 5, 6, 7, 8, 8, 8, 8, 9
You asked:
Find the arithmetic mean of the following data: \(1, 1, 1, 1, 2, 2, 3, 3, 4, 4, 4, 4, 5, 5, 6, 7, 8, 8, 8, 8, 9\)
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 \(1, 1, 1, 1, 2,...\) is \(\frac{94}{21} \approx 4.47619\).
