Question

1. what does a scatter plot primarily show?

a. the relationship between two variables
b. the division of data into categories
c. the difference between two sets of data
d. the sum of two variables

Explanation:

A scatter plot is a graph that uses dots to represent values for two different numeric variables. Each dot's position on the horizontal and vertical axis indicates values for an individual data point. It is mainly used to show the relationship between two variables. For example, if we have data on the height and weight of a group of people, a scatter plot can show how height and weight are related.

• Option b: Division of data into categories is more related to bar charts (for categorical data) or histograms (for grouped numerical data), not scatter plots.
• Option c: Showing the difference between two sets of data is not the main purpose of a scatter plot. Tools like side - by - side bar charts can be used for comparing differences more directly.
• Option d: The sum of two variables is not what a scatter plot represents. A scatter plot focuses on the paired relationship, not the arithmetic sum.

Answer:

a. The relationship between two variables
