What is the primary purpose of a scatter plot in EDA?

Solution (By Examveda Team)

Option A: To show the distribution of a single variable: This is usually done with histograms or box plots, not scatter plots.
Option B: To visualize relationships between variables: This is the main point of a scatter plot! Each point on the plot represents a pair of values for two different variables. By looking at the pattern of points, we can see if there's a correlation or relationship between them. For example, if as one variable increases, the other also tends to increase, that shows a positive relationship.
Option C: To display categorical data: Categorical data is better shown with bar charts or pie charts, not scatter plots.
Option D: To represent time series data: Time series data is usually displayed using line charts.

In simple terms: A scatter plot helps us see if two things are connected. If we plot "ice cream sales" versus "temperature," we might see that as the temperature goes up, ice cream sales also go up. The scatter plot lets us see that relationship.
