Construction of a Histogram for Continuous Frequency Distribution

Q. The following table gives the distribution of 40 students across the different levels of Intelligent Quotient. Draw the histogram for the data.

$\begin{array}{cccccccc}IntelligentQuotient\left(IQ\right)& 60-70& 70-80& 80-90& 90-100& 100-110& 110-120& 120-130\\ Numberofstudents& 3& 5& 6& 7& 9& 8& 2\end{array}$

Q. Marks of the 100 students are distributed in the grouped frequency distribution.

Marks (Class marks)	70	80	90	100
No. of Students (Frequency)	25	41	7	13

What is the class interval for the group having frequency 13?

1. 85 - 95
2. 95 - 105
3. 80 - 90
4. 90 - 100

Q. Do you agree with the statement? Give reasons
There is a difference between Histogram and Frequency Polygon

Q. To construct a histogram, Ankita observed the range of observations. She decided to divide that range into a number of parts. Then she does following calculation:
Range/no. of parts.

What are the terms used to describe
a. number of parts
b. range/no. of parts

1. number of bars, width of bars
2. frequency, class interval
3. intervals, class width
4. class, band width
