Which of the following chart is used to test the linear relationship between continuous variables?

Question

BlackTom AI · Accepted Answer

When assessing how to test the relationship between two continuous variables, we look for a plot that displays pairs of values to reveal patterns like linearity, direction, and strength.
Option 1: Histogram – This visualization shows the distribution of a single continuous variable, not the relationship between two variables, so it does not test linear relationship.
Option 2: All of the options – Since not every listed chart is appropriate for assessing a linear relationship (histograms and bar charts do not show two-variable relationships), this option is incorrect.
Option 3: Bar chart – Bar charts compare categories and their values, typically with one quantitative variable and a categorical one; they do not depict bivariate continuous relationships, so they’re not suitable for testing linearity.
Option 4: Scatter plot – This plot places each data pair on two axes, allowing visual inspection of how one variable changes with the other and enabling assessment of linear trends and correlation, which is exactly what is needed to test linear relationships between continuous variables.
Hence, the reasoning points to scatter plots as the appropriate tool for evaluating the linear relationship between two continuous variables.
