Analyzing Data Using Bivariate Correlation, Regression, and T-Tests
Null and Alternative Hypotheses: The null and alternative hypotheses for the bivariate
correlation analysis are as follows:
H0: ρ = 0 (correlation coefficient is 0; no association)
H1: ρ ≠ 0 (correlation coefficient is not 0; nonzero correlation could exist)
These hypotheses are used to test the strength and direction of the relationship between variables.
Scatterplot Relationship: The scatterplot visually depicts a positive relationship between the
variables, indicating that as one variable increases, the other tends to increase as well.
