### Null hypothesis for single linear regression

1. 1. Null-hypothesis for a Single-Linear Regression Conceptual Explanation
2. 2. With hypothesis testing we are setting up a null-hypothesis –
3. 3. With hypothesis testing we are setting up a null-hypothesis – the probability that there is no effect or relationship –
4. 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. 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. 6. Here is a template for a Single Linear Regression Null- Hypothesis:
7. 7. Template
8. 8. There will be no significant prediction of [insert dependent variable] by [insert predictor variable].
9. 9. Here is an example:
10. 10. You have been asked to investigate how well hours of sleep predicts ACT scores.
11. 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. 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. 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. 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. 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. 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. 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. 18. There will be no significant prediction of ACT scores by hours of sleep.
