These are just a few examples of what the research questions and hypotheses may look like when a regression analysis is appropriate.
Simple Linear Regression
- RQ: Does anxiety symptom severity influence relationship satisfaction?
- H0: Anxiety symptom severity does not have an influence on relationship satisfaction.
- Ha: Anxiety symptom severity has a significant influence on relationship satisfaction.
- RQ: Can a person's GRE score be used to predict their college GPA?
- H0: A person's GRE score does not predict their college GPA.
- Ha: A person's GRE score is a significant predictor of their college GPA.
Multiple Linear Regression
- RQ: Do attachment style, length of relationship, and communication type influence relationship security scores?
- H0: Attachment style, length of relationship, and communication type are not related to relationship security.
- Ha: At least one of the predictor variables is a significant predictor of relationship security.
- RQ: Are undergraduate GPA and use of support services useful in predicting academic success in graduate students?
- H0: There is no relationship between undergraduate GPA or use of support services, and academic success.
- Ha: Undergraduate GPA and/or use of support services significantly predict(s) academic success.
Logistic Regression
- RQ: Can you predict a person's gender based on income?
- H0: Income is not a predictor of gender.
- Ha: There is a predictive relationship between gender and income.
- RQ: Do customer satisfaction, brand perception, and price perception influence purchase decision?
- H0: There is no relationship between customer satisfaction, brand perception, price perception, and purchase decision.
- Ha: At least one of the predictor variables has a predictive relationship with purchase decision.
Multiple Logistic Regression
- RQ: Do standardized test scores in math, reading, and writing, influence game choice?
- H0: There is no influence on game choice by standardized test scores.
- Ha: There is a significant influence of at least one of the predictor variables on game choice.
