Question

In a histogram, the area of each rectangle is proportional to the class size of the corresponding class interval?
If true then enter $1$ and if false then enter $0$

• A. $1$
• B. $0$
• C. can't determine
• D. None of these

Answer 1

The correct option is B $0$

No, this is not a correct statement.
In a histogram, horizontal axis represents the class intervals whose width is fixed & the varying data is plotted along the y-axis. So in all the rectangles of a histogram, width remains same & the length changes.
So correct statement is "In a histogram, the area of each rectangle is proportional to the frequency of its class."
