Final answer:
In bivariate correlation, one variable plays the role of the independent variable and the other variable is the dependent variable. We use what we know about the relationship between the independent variable and the outcome variable to make predictions or draw conclusions.
Step-by-step explanation:
In bivariate correlation, one variable plays the role of the independent variable and the other variable is the dependent variable. We use what we know about the relationship between the independent variable and the outcome variable to make predictions or draw conclusions.
To illustrate this, let's consider an example where we want to examine the relationship between the number of hours studied (independent variable) and test scores (dependent variable). We collect data from a group of students and analyze the correlation between these two variables.
Using the data, we can draw a scatter plot, calculate the line of best fit (regression line), and find the correlation coefficient (r), which measures the strength and direction of the relationship.
