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 value 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 value 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).
Here is a template for writing a null-hypothesis for a Pearson Correlation:
Here is a template for writing a null-hypothesis for a Pearson Correlation:
There is no statistically significant relationship between the [insert independent variable] and [insert dependent variable].
