Most Essential Used Statistics Graphs

1). Pareto Diagram or Bar Graph

A Pareto diagram or bar graph is a way to visually represent qualitative data. The bars are arranged in order of frequency, so more important categories are emphasized.

2). Pie Chart or Circle Graph

Another common way to represent data graphically is a pie chart. By looking at all of the pie pieces, you can compare how much of the data fits in each category, or slice.

3). Histogram

A histogram in another kind of graph that uses bars in its display. This type of graph is used with quantitative data.

4). Stem and Leaf Plot

A stem and leaf plot breaks each value of a quantitative data set into two pieces. It provides a way to list all data values in a compact form.

5). Dot Plot

A dot plot is a hybrid between a histogram and a stem and leaf plot. It provide a good way to compare how long it takes a group of six or seven individuals to make breakfast.

6). Scatterplots

A scatterplot displays data that is paired by using a horizontal axis (the x-axis), and a vertical axis (the y-axis). The scatterplot helps you uncover more information about any data set.

7). Time-Series Graphs

A time-series graph displays data at different points in time, so it is another kind of graph to be used for certain kinds of paired data. This type of graph measures trends over time.
