Using Excel to do calculations
 You can calculate the means, variance, maximum, minimum of the marks at
the column C and column D. First, selecting the column, for example, the
column C in the following figure, and then click
to pull out the
operator of “Sum”, “Average”, etc.
 Choose , for example, “Average” , you will get average listed after the third
