  1. Ogive

  2. Histogram

  3. Frequency polygon

  4. None of these

Show answer
Correct Option: B
Explanation:

Answer:- B) Histogram

Reason:-
Histogram is easy to use and we can plot the curve, also we can find the areas of adjoining rectangles which is proportional to class frequencies.

When rectangles are drawn with the areas proportional to the frequencies of respective class intervals, what is the diagram called? 

maths bar graphs histograms for non-uniform class widths histograms with unequal class intervals revisiting histograms

  1. Bar graph

  2. Frequency polygon

  3. Pie graph

  4. Histogram

Show answer
Correct Option: D
Explanation:

The histograms are diagrams which represent the class interval and the frequency in the form of a rectangle. 

There will be as many adjoining rectangles as there are class intervals. 
So, when rectangles are drawn with the areas proportional to the frequencies of respective class intervals, the diagram called Histogram.
Therefore, option D is correct.

In histogram, the height of rectangle shows _____

maths bar graphs histograms for non-uniform class widths histograms with unequal class intervals revisiting histograms

  1. width of the class

  2. upper limit of the class

  3. lower limit of the class

  4. frequency of the class

Show answer
Correct Option: D
Explanation:

A histogram is a display of statistical information that uses rectangles to show the frequency of data items in successive numerical intervals of equal size.

Hence, height of the rectangle represents the frequency of the class.
