Question

A histogram consists of a set of adjacent rectangles whose bases are equal to ............ and heights are equal to .................. *



class range and class heights

class size and class frequencies

class value and class height

class frequency and class range

Answer 1

Answer:

Option 2 is the correct answer.

Answer 2

Option(b): A histogram consists of a set of adjacent rectangles whose bases are equal to class size and whose heights are equal to class frequencies.

• A histogram graph is a representation of data as a bar graph.
• A histogram is an area diagram.
• It can be defined as a set of rectangles with bases along with the intervals between class boundaries and with their areas proportional to frequencies in the corresponding classes.
• The height of each rectangle is proportional to the corresponding frequency of a same class.
• For different classes, the heights will be proportional to corresponding frequency densities.
• All the rectangles are adjacent since the base covers the intervals between class boundaries.

Hence, A histogram consists of a set of adjacent rectangles whose bases are equal to class size and heights are equal to class frequencies.
