Question

A geometric representation showing the relationship between a whole and its parts is a

• A. Pie chart
• B. Histogram
• C. Bar graph
• D. Pictograph

Answer 1

The correct option is A

Pie chart

A pie chart is a type of graph that represents the data in the circular graph. A pie chart divides the circular statistical graphic into sectors or slices in order to illustrate the numerical problems. Each sector denotes a proportionate part of the whole. In a Pie Chart, the sector is used to represent data.

• A histogram is a diagram involving rectangles whose area is proportional to the frequency of a variable and width is equal to the class interval.
• The pictorial representation of grouped data, in the form of vertical or horizontal rectangular bars, where the lengths of the bars are equivalent to the measure of data, are known as bar graphs or bar charts.
• Pictographs define the frequency of the data using images or symbols, which are relevant to the data. The pictograph is extremely easy to understand, and it is one of the simplest ways to represent the statistical data.

Hence, option (A) is correct.
