Solution :

A Histogram is most appropriate for displaying interval-ratio level data.

A Histogram visualises the distribution of data over a continuous interval or certain time period. Each bar in a histogram represents the tabulated frequency at each interval/bin.

For nominal/ordinal data, use pie charts and bar charts.

For interval/ratio variables, use histograms (bar charts of equal interval).

Frequency polygons are good choice for displaying cumulative frequency distributions.They serve the same purpose as histograms, but are especially helpful for comparing sets of data.

A pie chart shows how a total amount is divided between levels of a categorical variable as a circle divided into radial slices. Each categorical value corresponds with a single slice of the circle, and the size of each slice (both in area and arc length) indicates what proportion of the whole each category level takes.

A bar chart or bar graph is a chart or graph that presents categorical data with rectangular bars with heights or lengths proportional to the values that they represent.
