Question

3 which type of graph provides a visual representation of one quantitative variable in relation to a second quantitative variable?
options: bar graph, line graph, circle graph, table

Explanation:

To determine the correct graph type, we analyze each option:

• A bar graph is used to compare different categories or groups, not to show the relationship between two quantitative variables.
• A line graph is designed to display the relationship between two quantitative variables (e.g., time on the x - axis and a measured quantity on the y - axis), showing how one variable changes in relation to the other.
• A circle graph (pie chart) is used to show the proportion of different parts to a whole, not the relationship between two quantitative variables.
• A table is a tabular representation of data, not a graph that visually represents the relationship between two quantitative variables.

Answer:

B. Line graph
