Question

If x1, x2, x3,….., xn are the observations of a given data. Then the mean of the observations will be:​

Answer 1

x1 + xn / 2 = mean of given observation

Answer 2

If x1, x2, x3,….., xn are the observations of a given data. Then the mean of the observations will be (x1, x2, x3,….., xn) / n.

• The mean of the observations is the average of the observation given in the series.
• It is calculated by adding the sum of all the observations given in the series and then dividing it by the total number of observations.
• In the given question, the sum of all observations will be (x1, x2, x3,......, xn) and then dividing it by n as the total number of observations is n.
