Answer – The means ,know as Average, is the average of all points in discrete or continuous distribution. The method of calculating this mean is different for discrete distribution and continuous distribution. This average calculated is called mean or mathematical average. It is easy to calculate the mean by discrete data by adding all the numbers from X1 to Xn and divide it by X1 + X2 + … / Xn. On the other hand, from continuous distribution, one has to use a formula to calculate the mean and generally there are more than one way to calculate the mean by continuous distribution. Average can be calculated for grouped and uncontrolled data. This is the only remedy for central tendency based on all the points in the series.
