- 4. • A pictograph is a way to represent data using images. Each image in the pictograph represents a certain number of things. In other words, a pictograph uses pictures and symbols to convey information about the provided data.
- 6. • 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. The bars can be plotted vertically or horizontally. A vertical bar chart is sometimes called a column chart.
- 8. • The line chart is a simple, two-dimensional chart with an X and Y axis, each point representing a single value. The data points are joined by a line to depict a trend, usually over time.
- 10. • Pie Chart is a circular representation of data. It is called a pie chart because the sectors of the circles are just like the slices of a pie. The area within each sector (slice) represents the size of the data. The area of each sector is directly proportional to the frequency of the data.
- 12. • A histogram is a graph used to represent the frequency distribution of a few data points of one variable. Histograms often classify data into various “bins” or “range groups” and count how many data points belong to each of those bins. • A histogram has an appearance similar to a vertical bar chart, but there are no gaps between the bars. Generally, a histogram will have bars of equal width.
