Q6 of 35 Page 195

Let us observe the following cumulative frequency distribution table and construct a frequency distribution table:

lower class boundary = lower limit - 0.5

Upper class boundary = upper limit + 0.5


Mid value of class


class - size = upper class boundary – lower class boundary


Frequency density = class frequency of that class/class size



The class - limit in this table is exclusive type
