(a) Histogram

(b) Pie graph

(c) Line graph

(d) Stacked bar graph

The question was posed to me in an interview for job.

The question is from Data Handling topic in portion Data Handling of Mathematics – Class 8

Answer 1

Correct choice is (b) Pie graph

Best explanation: The correct answer is pie graph as pie graph represents relationship between whole and its parts. Histogram is represented with bars of equal width with no gap between adjacent bars. The height of the bar represents the number of data items in the given data range called frequency. Line graph is a line joining all the data points. A stacked bar graph is a chart that uses bars to show comparisons between categories of data with ability to break down and compare parts of a whole.
