How do you make a hypothesis?
In order to be able to set up a hypothesis, you must observe the following criteria: Both variables must be measurable. If you formulate several hypotheses, they must not contradict each other. Scientific assumptions must be able to be refuted. Hypotheses must be formulated objectively and concisely.
When is Ho rejected?
Accepting or rejecting H0 does not mean that H0 is true or false, just that that decision was the most expedient in the circumstances. One chooses what one suspects or wants to have confirmed as the alternative hypothesis, and what one wants to reject as the null hypothesis.
When is a study significant?
If a statistical result is designated as significant, this expresses the fact that the probability of error that an accepted hypothesis also applies to the population is not above a specified level.
Which P value is significant?
A p-value of at most 5% or 1% is usually aimed for. That is, the difference between two groups would then be statistically significant with 1-p = 95% or with a probability of 99%.
What does the P value tell me?
1 Definition The p-value is the probability that the test statistic (= test variable, test variable, test function) – if the null hypothesis (H0) is valid – assumes at least the value calculated in the sample (i.e. this value or a larger value). The p-value is often given by statistical software.
