Unit 8 AS1: Hypothesis Testing
Problem statements become research hypotheses when constructs are operationalized. A hypothesis is a theory or proposition set forth as an explanation for the occurrence of some observed phenomenon that can be used to guide investigation. A working hypothesis can be considered as being highly probable in lieu of the established facts. A scientific hypothesis can become a theory if it is proven by repeatable experiments. Hypothesis testing is common in statistics as a method of making decisions using data. Testing a hypothesis is trying to determine if your observation of some phenomenon is likely to have really occurred based on statistics.
The hypothesis is a clear statement of what was intended to be investigated. Students are to submit a two-paragraph paper that clearly states the hypothesis of the research proposal. The hypothesis should predict the anticipated outcome of the proposed study and must be testable. Identify whether it is a null hypothesis or alternative hypothesis and state the expected relationship between the variables or if they are consistent with the existing body of knowledge. The hypothesis should be expressed as simply and concisely as possible.
