Null hypothesis for single linear regression

1. Null-hypothesis for a
Single-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 Single-Linear
Regression you are attempting to determine the
predictive power of one independent variable (hours of
sleep) on a dependent variable (test scores).

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

7. Template

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

9. Here is an example:

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

11. 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]

12. 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]

13. 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]

14. 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]

15. 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 ACT scores by
[insert predictor variable]

16. 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 ACT scores by
[insert predictor variable]

17. 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 ACT scores by
hours of sleep.

18. There will be no significant prediction of ACT
scores by hours of sleep.
