What Type of Graph Shows Qualitative Data?


Scott Campbell

When it comes to displaying qualitative data, there are several types of graphs that can effectively represent the information. In this article, we will explore some of the most commonly used graph types for qualitative data and discuss their advantages and limitations.

Bar Graphs

Bar graphs are a popular choice for displaying qualitative data. They consist of rectangular bars that represent different categories or groups. The height of each bar corresponds to the frequency or count of the category it represents.

Bar graphs are visually engaging and allow for easy comparison between different categories. They are particularly useful when the data is discrete and non-numeric. For example, you can use a bar graph to show the number of students in each grade level at a school.

Pie Charts

Pie charts are another commonly used graph type for qualitative data. They display data as slices of a circle, with each slice representing a different category or group. The size of each slice is proportional to the percentage or proportion it represents in relation to the whole.

Pie charts are great for showing proportions and percentages, making them ideal for displaying survey results or market shares. However, they can become visually cluttered when there are too many categories or when the differences between categories are small.

Line Graphs

While line graphs are typically used to display quantitative data over time, they can also be effective for showing qualitative data trends. In this case, instead of plotting numerical values on the y-axis, you would plot categorical data.

A line graph can be particularly useful when you want to illustrate trends or changes in qualitative data over time or across different conditions. For example, you could use a line graph to show how customer satisfaction levels have evolved over different quarters.

Scatter Plots

Scatter plots are commonly used to display relationships between two quantitative variables, but they can also be adapted to represent qualitative data. In this case, the x-axis and y-axis would represent different categories or groups.

Scatter plots are useful when you want to show the distribution or clustering of qualitative data points. For example, you could use a scatter plot to display the locations of different species of plants in a nature reserve.


Choosing the right type of graph to display qualitative data depends on the specific information you want to convey. Bar graphs are great for comparing frequencies, pie charts are ideal for showing proportions, line graphs illustrate trends over time or conditions, and scatter plots display distributions or clusters of data points.

Remember to consider the advantages and limitations of each graph type when deciding which one will best represent your qualitative data. By choosing the appropriate graph and utilizing HTML styling elements like bold text, underlined text,
