Answer 1

Correct Answer: Scatter Plot

Rationale:

A scatter plot is a type of graph that uses Cartesian coordinates to display values for typically two variables for a set of data. The data is displayed as a collection of points, each having the value of one variable determining the position on the horizontal axis and the value of the other variable determining the position on the vertical axis.
This type of graph is used to observe and show relationships between two numeric variables. The data points can show how one variable is affected by another, and the pattern of points can indicate the strength and direction of the relationship.

Explanation of Other Options:

Pie Chart

Rationale: A pie chart is a circular statistical graphic, which is divided into slices to illustrate numerical proportion. Each slice of the pie chart represents a category and its size is proportional to the percentage of the total it represents. Pie charts are not suitable for showing relationships between variables.

Bar Diagram

Rationale: A bar diagram, or bar chart, represents categorical data with rectangular bars with heights or lengths proportional to the values that they represent. Bar diagrams are used to compare different categories of data, but they do not show relationships between two variables as scatter plots do.

Line Graph

Rationale: A line graph is used to display information that changes over time. It is plotted by connecting data points with straight lines. While line graphs can show trends over time and relationships between variables, they are typically used for continuous data rather than individual data points, unlike scatter plots.

Conclusion:

Among the given options, a scatter plot is the appropriate graph for displaying and analyzing the relationship between two numeric variables. It helps in identifying the correlation and pattern of data points effectively.
