how to calculate central tendency in excel

The type of function, the general tendency demonstrated by the function tted to the data, relative likelihood and the mean square errors (MSE), for each model and time bin. Property 1: If x is the mean of sample {x1, x2, , xm}and is the mean of sample {y1, y2, , yn}then the mean of the combined sample is, Similarly, if x is the mean of population {x1, x2, , xm}and y is the mean of population {y1, y2, , yn}then the mean of the combined population is. But the procedures for calculating the population and sample means are the same.
