For example: While there are many ways to state a hypothesis, you may wish to revise your first hypothesis in order to make it easier to design an experiment to test it.
For example, let's say you have a bad breakout the morning after eating a lot of greasy food.
You may wonder if there is a correlation between eating greasy food and getting pimples.
You propose a hypothesis: Next, you need to design an experiment to test this hypothesis.
(The alternate hypothesis): μ (the average) ≠ (is not equal to) 8.2 That’s How to State the Null Hypothesis! ------------------------------------------------------------------------------ Need help with a homework or test question?
With Chegg Study, you can get step-by-step solutions to your questions from an expert in the field. - Includes many concepts such as sample size, hypothesis tests, or logistic regression, explained by Stephanie Glen, founder of Statistics How To. This seemingly obvious aspect of research can be deceptively difficult to pin down, as researchers often have an unstated sense of what they want to achieve in a study (and excitement about doing so) that makes it challenging to clearly state a research question.Glenn Firebaugh (2008) identified two key criteria for research questions: questions must be researchable and they must be interesting.During these sessions, students can get answers to introduction to the problem, background of study, statement of the problem, purpose of the study, and theoretical framework.Questions may also involve title searches, literature review, synthesis of findings, gap and critique of research.If you set out to prove an alternate hypothesis without considering it, you are likely setting yourself up for failure.At a minimum, your experiment will likely not be taken seriously. Several scientists, including Copernicus, set out to disprove the null hypothesis.Let's say you decide to eat greasy food every day for a week and record the effect on your face. So, if you eat fatty food every day for a week and suffer breakouts and then don't breakout the week that you avoid greasy food, you can be pretty sure something is up. Probably not, since it is so hard to assign cause and effect.Then, as a control, for the next week, you'll avoid greasy food and see what happens. However, you can make a strong case that there is some relationship between diet and acne.Including both a null and an alternate hypothesis is one safeguard to ensure your research isn’t flawed.Not including the null hypothesis in your research is considered very bad practice by the scientific community.
