Question

A pie chart is:
(A) A chart demonstrating the increasing incidence of obesity in society
(B) Only used in catering management research
(C) Any form of pictorial representation of theta
(D) All illustration where the data are divided into proportional segments according to the share each has of the total value of the data

Answer 1

Hint: In this question, we have to choose the correct particular from the given options.
We need to first consider the definition of the pie chart then choose the correct option for pie chart which is actually appropriate.

Complete step-by-step solution:
We need to choose the correct particular from the given options.
Considering the definition we have,
A pie chart (or a circle chart) is a circular statistical graphic, which is divided into slices to illustrate numerical proportion. In a pie chart, the arc length of each slice (and consequently its central angle and area), is proportional to the quantity it represents.

Option (D) is the correct answer.

Note: Graphical representation:
Graphical representation refers to the use of charts and graphs to visually display, analyse, clarify, and interpret numerical data, functions, and other qualitative structures. Data is ingested into graphical representation of data software and then represented by a variety of symbols, such as lines on a line chart, bars on a bar chart, or slices on a pie chart, from which users can gain greater insight than by numerical analysis alone.
Pie charts are very widely used in the business world and the mass media. A Pie Chart is a type of graph that displays data in a circular graph. The pieces of the graph are proportional to the fraction of the whole in each category. In other words, each slice of the pie is relative to the size of that category in the group as a whole.
