Question
For categorical data which types of graph/charts we use.
- Stem-and-leaf display
- Pareto chart
- Polygon
- Ogive
Solution
For categorical data, we typically use the following types of graphs/charts:
-
Bar Graphs: These are the most common type of graphs used for categorical data. Each category is represented by a bar and the size of the bar represents its corresponding value.
-
Pie Charts: These are used when we want to show the data as a part of a whole. Each category is represented by a slice of the pie.
-
Pareto Charts: This is a type of bar graph where categories are plotted in decreasing order of their frequencies or proportions. It also includes a line graph which shows the cumulative total.
Stem-and-leaf displays, polygons, and ogives are typically used for numerical data, not categorical data. Stem-and-leaf displays are used to organize numerical data and show its distribution. Polygons (frequency polygons) are used to show the shape of the distribution for a continuous variable. Ogives (cumulative frequency graphs) are used to show how the cumulative frequency changes with the variable.
