Draw a histogram to represent the following information:
Solution:
Here the class intervals are of unequal size. So, we calculate the adjusted frequency using the formula,
Adjusted freq $=\frac{\min \text { class size }}{\text { class size of this class }} \times$ freq
Class sizes are
$10-5=5$
$15-10=5$
$25-15=10$
$45-25=20$
$75-45=30$
Minimum class size = 5
