Correlation Hypothesis Test Printable The correlation coefficient r tells us about the strength and direction of the linear relationship between X 1 and X 2 The sample data are used to compute r the correlation coefficient for the sample If we had data for the entire population we could find the population correlation coefficient
Hypothesis Test for Correlation Learning Outcomes Conduct a linear regression t test using p values and critical values and interpret the conclusion in context The correlation coefficient r tells us about the strength and direction of the linear relationship between xand y To determine if a correlation coefficient is statistically significant you can perform a t test which involves calculating a t score and a corresponding p value The formula to calculate the t score is t r n 2 1 r2 where r The correlation coefficient n The sample size

The formula for the t test statistic is t frac b 1 sqrt left frac MSE SS xx right Use the t distribution with degrees of freedom equal to n p 1 The t test for slope has the same hypotheses as the F test H 0 beta 1 0 H 1 beta 1 neq 0

Summary At the 5 significance level there is enough evidence to support the claim that there is a statistically significant linear relationship correlation between the number of hours studied for an exam and exam scores The p value method could also be used to find the same decision

In general a researcher should use the hypothesis test for the population correlation to learn of a linear association between two variables when it isn t obvious which variable should be regarded as the response Let s clarify this point with examples of two different research questions

The hypothesis test lets us decide whether the value of the population correlation coefficient is close to zero or significantly different from zero We decide this based on the sample correlation coefficient r and the sample size n

Students are required to perform hypotheses tests for correlation coefficients The hypotheses need to be stated in terms of where represents the population correlation coefficient All tests should have the null hypothesis H0 0 Tables of critical values or a p value will be given to students
We perform a hypothesis test of the significance of the correlation coefficient to decide whether the linear relationship in the sample data is strong enough to use to model the relationship in the population The sample data are used to compute r the correlation coefficient for the sample Theorem 1 Suppose r1 and r2 are as in the Theorem 1 of Correlation Testing via Fisher Transformation where r1 and r2 are based on independent samples and further suppose that 1 2 If z is defined as follows then z N 0 1 where Proof By Theorem 1 of Correlation Testing via Fisher Transformation for i 1 2
Hypothesis Testing Correlations Hypothesis Tests with the Pearson Correlation We test the correlation coefficient to determine whether the linear relationship in the sample data effectively models the relationship in the population Learning Objectives
