Null hypothesis for multiple linear regression

Null hypothesis for multiple linear regression

1. Null-hypothesis for a Multiple-Linear Regression Conceptual Explanation

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

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

4. 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.

5. As you may recall, when running a Multiple-Linear Regression you are attempting to determine the predictive power of more than one independent (hours of sleep, study time, gender, family background, etc.) on a dependent variable (test scores).

6. Here are two templates for a Multiple Linear Regression Null-Hypotheses:

7. Template #1

8. There will be no significant prediction of [insert dependent variable] by [insert predictor variable 1] and [insert predictor variable 2], etc.
