SOLUTION

TO CHOOSE THE CORRECT OPTION

Frequency density corresponding to a class interval is the ratio of

a) Class frequency to the total frequency

b) Class frequency to the class length

c) Class length to the class frequency

d) Class frequency to the cumulative frequency

CONCEPT TO BE IMPLEMENTED

CLASS INTERVAL

When the number of sample values are large in number and are in wide range, then the whole data is divided in a number of several groups according to the size of the sample. Each of these groups, made as above, is known as class interval

CLASS LENGTH

Length of the class interval of an class is defined to be the difference between the lower and upper class boundaries ( not class limits) of that particular class interval.

Class length = Upper Class boundary - Lower class boundary

CLASS FREQUENCY

The number of observed values falling within a class is called the frequency of that class

EVALUATION

FREQUENCY DENSITY

Frequency density of any class is defined as its frequency per unit width

Hence Frequency density is given by the formula

 \displaystyle \sf{Frequency  \:  \: Density  =  \frac{Class \:  \:  Frequency}{Class \:  Length }  }

Frequency density corresponding to a class interval is the ratio of

b) Class frequency to the class length
