Scatterplots

Scatterplots are a type of data visualization that shows the relationship between two numerical variables. They are created by plotting the values of one variable on the x-axis and the values of the other variable on the y-axis. Each point on the scatterplot represents a single data point, and the pattern of the points can reveal trends and relationships between the variables.

Why Learn About Scatterplots?

Scatterplots are a powerful tool for understanding data because they can reveal relationships that would not be obvious from looking at the data in a table or list. For example, a scatterplot might show that there is a positive relationship between the amount of money people spend on education and their income. This relationship would not be obvious from looking at the data in a table, which would only show that people with more money tend to have more education. However, the scatterplot would allow us to see that the relationship is not linear, and that there is a point at which the relationship starts to break down.

Scatterplots can also be used to identify outliers in data. Outliers are data points that are significantly different from the rest of the data. They can be caused by errors in data collection or entry, or they can represent real-world phenomena. Outliers can be interesting and informative, but they can also make it difficult to see the overall trend of the data. Scatterplots can help us to identify outliers so that we can investigate them further and determine whether or not they are valid.
