WebSep 27, 2024 · It is a measure of the central location of data in a set of values which vary in range. In Python, we usually do this by dividing the sum of given numbers with the count of number present. Given set of numbers : [n1, n2, n3, n5, n6] Sum of data-set = (n1 + n2 + n3 + n4 + n5) Number of data produced = 5 Average or arithmetic mean = (n1 + n2 + n3 ...

WebIn Maths, an average of a list of data is the expression of the central value of a set of data. Mathematically, it is defined as the ratio of summation of all the data to the number of units present in the list. In terms of statistics, the average of a given set of numerical data is also called mean. For example, the average of 2, 3 and 4 is (2 ...
