What is the formula for the arithmetic mean?(a) \(\frac {Number \, of \, the \, observations}{Sum \, of \, observations}\)(b) \(\frac {Sum \, of \, the \, observations}{Number \, of \, observations}\)(c) \(\frac {Product \, of \, the\, observations}{Number \, of \, observations}\)(d) \(\frac {Sum \, of \, the \, observations}{Product \, of \, the \, observations}\)This question was addressed to me by my college director while I was bunking the class.This is a very interesting question from Statistics topic in chapter Statistics of Mathematics – Class 10

Answer»

The CORRECT choice is (b) \(\frac {Sum \, of \, the \, observations}{Number \, of \, observations}\)

Explanation: Arithmetic MEAN can also be called the AVERAGE of given variables in a distribution. The formula for arithmetic mean is the ratio of the sum of the observations to the number of observations.

Arithmetic mean = \(\frac {Sum \, of \, the \, observations}{Number \, of \, observations}\)
