 Tools & Examples For Comparing Numbers 

Data Visualizations

Data Visualizations are useful when you are comparing numbers because they help you see differences, patterns, and relationships that can be found in the data that is being presented. These visuals help highlight trends that can be overlooked, giving the viewer or reader a quick and easy understanding of values that can be increasing or decreasing over time. 

Bar Chart 

Bar Charts are most useful when you are doing a side-by-side comparison. For example, crime rates in different cities. Comparing the lengths of the bar charts makes the data easy to understand when determining which values are higher or lower in relation to the data being presented. Beside is a bar chart that demonstrates the Crime Rate in Chicago in 2018. 

Line Graph 

Line graphs are best when comparing numbers over a series of time. For example, any sort of monthly unemployment rates or population growth. Line graphs are best to demonstrate trends, and when there is an increase or a decrease that needs to be shown visually.

Above is a line graph representing the Population Growth in the United States from year 1900-2000. The population is measured on the y-axis of the graph in millions.
