Explanation

A scatter plot is a type of graph used in Exploratory Data Analysis (EDA) to visualize the relationship between two continuous variables. It displays the data points as points on a coordinate grid, with the x-axis representing one variable and the y-axis representing the other.

The primary purpose of a scatter plot is to:

  • Show the strength and direction of the relationship between the two variables
  • Identify patterns, correlations, or outliers in the data
  • Help identify potential relationships that may not be immediately apparent from looking at individual variables

Scatter plots are particularly useful for:

  • Identifying linear or non-linear relationships
  • Identifying clusters or groups in the data
  • Identifying outliers or anomalies
