Null hypothesis for pearson correlation

Null-hypothesis for a Pearson Product Moment Correlation

Conceptual Explanation

With hypothesis testing we are setting up a null-hypothesis –

With hypothesis testing we are setting up a null-hypothesis – the probability that there is no effect or relationship –

With hypothesis testing we are setting up a null-hypothesis – the probability that there is no effect or relationship – and then we collect evidence that leads us to either accept or reject that null hypothesis.

As you may recall, a Pearson Product Moment Correlation or simply Pearson Correlation is a tool that makes it possible to statistically test the relationship between two continuous variables.

As you may recall, a Pearson Product Moment Correlation or simply Pearson Correlation is a tool that makes it possible to statistically test the relationship between two continuous variables. By continuous we mean a number that can take any value between two points (e.g., weight between 150 to 250 pounds).
