Why is a null hypothesis required in research?
Psychology homework help
Assignment 3: Course Project Task I
Research Question and Hypothesis
After reading the feedback on your proposed quantitative research question in M1 Assignment 2, provide your revised quantitative research question. Next, develop a hypothesis for the research question (Include a null and an alternative hypothesis for your question.).
Keep in mind that a hypothesis is a specific statement of prediction. A hypothesis describes in concrete (rather than theoretical) terms what you expect will happen in your study. It should be testable and often mirrors the research question in the way that it is written.
For example, there is a positive correlation between having an alcoholic parent and alcoholism in adulthood.
Once you have clearly stated your research question and hypothesis, discuss the following (in 1–2 pages):
· Why is a null hypothesis required in research? How is the null hypothesis used when drawing conclusions from the collected data?
· What is the relationship of your hypothesis to the identified problem?
· How is your hypothesis feasible?
· How is your hypothesis measurable and testable?
Submission Details:
· By the due date assigned, save your hypothesis and supporting discussion as M1_A3_Lastname_Firstname.doc and submit it to the Submissions Area.
