Why is a null hypothesis required in research


Project Assignment: Research Question and Hypothesis

Task I

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?

Format your assignment according to the following formatting requirements:

1. The answer should be typed, double spaced, using Times New Roman font (size 12), with one-inch margins on all sides.

2. The response also include a cover page containing the title of the assignment, the student's name, the course title, and the date. The cover page is not included in the required page length.

3. Also Include a reference page. The Citations and references should follow APA format. The reference page is not included in the required page length.
