Scatter

What type of data does a scatter plot represent?

Scatter plots represent the correlation or relationship between two numerical variables. They are a valuable tool for exploratory data analysis, helping you to identify potential relationships, outliers, and patterns in your data.

Each dot on the plot represents a single data point:

• Position on the x-axis is determined by the value of one variable

• Its position on the y-axis is determined by the value of the other variable.

There can be a:

• Positive correlation: Dots slope upwards from left to right, indicating that as one variable increases, the other also tends to increase.

• Negative correlation: Dots slope downwards from left to right, indicating that as one variable increases, the other tends to decrease.

• No correlation: The dots are scattered randomly, suggesting no clear relationship between the two variables.

Some data types represented by a scatter plot:

• Height and weight of individuals

• Advertising spending and sales revenue

• Temperature and ice cream sales

• Study hours and exam scores
