Question

Following is the frequency distribution of the total marks obtained by the students of all sections of a class in an examination. ​
Draw a histogram to represent the provided data.​

Answer 1

Class width = Upper limit – Lower limit
For $100-150$
Class width $=150-100=50$
Similarly,
Class width of $150-200=50$
Class width of $200-300=100$
Class width of $300-600=300$
Class width of $600-800=200$
Now,
$Adjusted$ $frequency$ = $\frac{minimumclasssize}{classsizeofthisclass}\times frequency$

Here, the minimum class size $=50$.
Now,
Adjusted frequency of class interval $300-600$ is.
$Adjusted$ $frequency$ = $\frac{50}{300}\times 60$ $=10$.
Similarly,
Adjusted frequency of $100-150=60$
Adjusted frequency of $150-200=70$
Adjusted frequency of $200-300=50$
Adjusted frequency of $600-800=45$

Taking,
$X-axis=1unit=50marks$
$Y-axis=1unit=10student$
Histogram of the above data is.
