Mean 2 10 12 8 5 14 3714 264. Get the sum of all the frequencies f and the sum of all the fx. The mean mu is the sum of divided by which is the sum of frequencies.
Solution for Calculate the sample mean and sample variance for the following frequency distribution of heart rates for a sample of American adults.
In such a distribution the frequency number of observations given in the set of data is discrete in nature. The mean mu is the sum of f M f M divided by n n which is the sum of frequencies. Mean 2 1 5 2 4 3 2 4 1 5 2 5 4 2 1. In such a distribution the frequency number of observations given in the set of data is discrete in nature.
