a) construct the frequency distibution with suitable number of class and class width.
b) draw: histogram ,frequency polygon, less then and more than ogive curves.
c) from the constructed frequency distribution, compute: Arithmetic mean, the geometric mean, harmonic mean, median, the mode, variance and standard deviation.​
