Question

To conduct a statistical test,you first need a ______.
A) P-value
B) A probability
C) A model
D) Null hypothesis

Accepted Answer

To conduct a statistical test, the first thing you need is a null hypothesis. This is the statement that you are trying to test, and it represents the idea that there is no significant difference between the groups being compared. Once you have a null hypothesis, you can then collect data and use statistical methods to determine whether or not it can be rejected in favor of an alternative hypothesis. The other options, such as a p-value, probability, and model, are all important components in statistical testing, but they come into play after you have established your null hypothesis.
