Steps to calculate Arithmetic Mean: Find the sum of all the observations. Multiply the frequency with its corresponding value and add them. This step is applicable only in the case of discrete and continuous series. Find the number of observations. However, in the case of discrete and continuous series, we add up all the frequencies.
Step 1 – Calculate the mean, median or mode value of the given data set. Step 2 – Then we must find the absolute difference between each value in the data set with the mean, ignoring the signs. Step 3 – We then sum up all the deviations. Step 4 – Finally, we find the mean or average of those values found in Step 3.
Formula for Arithmetic Mean. Mean = Sumofallobservations numberofobservations. Thus, the mean of n observation x 1, x 2, . . ., x n, is given by. x¯¯¯ = x1+x2+….+xn n = ∑n i=1 xi. Where the symbol ∑ called sigma which stands for summation. Suppose you want to find the mean score of all the tests you gave in this month. Marks.
