Null-hypothesis for a Single-Linear Regression

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, when running a Single-Linear Regression you are attempting to determine the predictive power of one independent variable (hours of sleep) on a dependent variable (test scores).

Here is a template for a Single Linear Regression Null-Hypothesis:

Template

There will be no significant prediction of [insert dependent variable] by [insert predictor variable].

Here is an example:

You have been asked to investigate how well hours of sleep predicts ACT scores.

Null-hypothesis for this problem:

You have been asked to investigate how well hours of sleep predicts ACT scores.

There will be no significant prediction of [insert dependent variable] by [insert predictor variable]
