a) Determine the number, n, in the sample.
b) Define k class intervals (co, C1] , (C1, C2] , ..., (Ck-1, Ck] .
c) Determine the frequency, fi, of each class i.
d) Calculate the relative frequency (proportion) of each class.
e) Draw frequency histogram. (For a frequency histogram: draw a rectangle for each class with
the class interval as the base and the height equal to the frequency of the class.)
f) Draw relative frequency histogram. (For a relative frequency histogram, draw a rectangle for
each class with the class interval as the base and the height equal to the relative frequency of
the class.
g) Draw density histogram. (For a density histogram, draw a rectangle for each class with the
class interval as the base and the height equal to h(x) =
