Explain direct method of calculating mean

1.	Explain direct method of calculating mean
Answer» 1. Direct MethodIn this method, the formal definition of mean is used. The values of items are simply summed and divided by the number of observations.Mean=∑X÷NThe formula for the direct method is as follows:Mean=\xa0∑fX/∑fHere,\xa0∑fX= Summation of the product of values of items with their corresponding frequencies∑f= Summation of all the frequencies<br>Mean (or average) of observations, as we know, is the sum of the values of all the observations divided by the total number of observations. If x1, x2,… + fn xn, and the number of observations = f1 + f2 + . . . ... + fn.
