If x1, x2, x3,….., xn are the observations of a given data. Then the mean of the observations will be:
A. Sum of observations/Total number of observations
B. Total number of observations/Sum of observations
C. Sum of observations +Total number of observations
D. None of the above
Answer:A
If x1, x2, x3,….., xn are the observations of a given data. Then the mean of the observations will be:
A. Sum of observations/Total number of observations B. Total number of observations/Sum of observations C. Sum of observations +Total number of observations D. None of the above
Explanation: The mean or average of observations will be equal to the ratio of sum of observations and total number of observations.
