In general, a frequency distribution should have at least 8 class groups but no more than 20.

Accepted Answer

The number of class groups in a frequency distribution can vary widely depending on the data set and the level of detail desired. There is no strict rule that limits the number of classes to a minimum of 8 or a maximum of 20. The choice often depends on the size of the data set and the purpose of the analysis.

Question 16

A polygon can be constructed from a bar chart.

Accepted Answer

A polygon is a plane figure that is described by a finite number of straight line segments connected to form a closed polygonal chain or polygonal circuit. A bar chart, however, represents data with rectangular bars and does not form a closed polygonal shape, making it impossible to construct a polygon directly from a bar chart.
