2. Null Hypothesis (H0) The null hypothesis is the “no effect” hypothesis. It’s the default assumption that there’s no relationship or difference between variables. Researchers use it to test if their results are significant enough to reject it. Null Hypothesis Example: Example:“There is...
If you’ve noticed that watering your plants every day makes them grow faster, your hypothesis might be “plants grow better with regular watering.” From there, you can begin experiments to test your hypothesis; in this example, you might set aside two plants, water one but not the other,...
Alternative Hypothesis: Proposes a specific relationship between variables, often used in contrast to the null hypothesis. Non-Directional Hypothesis: Suggests that there is a relationship between variables but does not define the nature of the relationship.Associative...
The Next Stage - What to Do with the Hypothesis Once you have yourhypothesis, the next stage is todesign the experiment, allowing a statistical analysis of data, and allowing you totest your hypothesis. The statistical analysis will allow you to reject either the null or the alternative hypoth...

You then test this nondirectional alternative hypothesis against the null hypothesis: H0: The only lab-tested drug has no effect on anxiety levels in an anxiety mouse model. In most research papers, the hypothesis or statement of purpose is placed at the end of the Introduction section. How ...
Physicians' Behavior and Their Interactions With Drug Companies: A Controlled Study of Physicians Who Requested Additions to a Hospital Drug Formulary OBJECTIVE: It is controversial whether physicians' interactions with drug companies affect their behavior. To test the null hypothesis, that such interact...
This allows a parametric test to be carried out in order to The null hypothesis The null hypothesis is an a priori statement of impartiality, prior to analysis, which states that when testing two samples, it is assumed that these come from the same population and that they are not ...
Null Hypothesis Anull hypothesisasserts that the two variables have no statistically significant relationship. It aims to disprove the hypothesis; for example, Little Susie's null hypothesis is that there will be no difference in the growth of a flower based on what type of water you use to wa...
The data were analyzed by using t-test formula. From the calculation, it was found that the t-test value is 14.84 when was higher than the t-table value (2.03). Therefore, the null hypothesis (Ho) is rejected and alternative hypothesis (Ha) is accepted. Thus, it can be concluded that...
