Study Notes

Hypothesis Overview

A hypothesis is a tentative prediction about the relationship between two or more variables in a population.
It translates a research question into a prediction of expected outcomes.
A hypothesis can be accepted or rejected based on research findings.

Kinds of Hypotheses

Simple Hypothesis
- Predicts a relationship between one independent variable and one dependent variable.
- Example: The nature of teachers correlates with the nature of students; the level of exercise impacts weight retention among elementary children.
Complex Hypothesis
- Predicts relationships between two or more independent variables and two or more dependent variables.
- Example: There is no significant relationship between the profile and management skills of Sunday school teachers and school performance; personal and professional profiles of coordinators affect teacher performance.
Directional Hypothesis
- Specifies the existence and direction of the relationship between independent and dependent variables.
- Example: Types of promotional campaigns positively impact customer patronage; higher fiber intake is associated with lower physical mass weight.
Non-directional Hypothesis
- Does not stipulate the direction of the relationship between independent and dependent variables.
- Example: Women with varying levels of postpartum depression differ regarding weight retention; hours spent reviewing correlate with performance levels in exams.
Null Hypothesis
- Formulated for statistical analysis; always expressed as a negative statement.
- Subjected to testing to determine if any significant effect exists.
- Example: No significant relationship between reasons for using alternative medicine and patient comfort; traits of middle-level managers do not significantly affect food chain productivity levels.
