Question
What is a null hypothesis??
- Assuming that the chi-squared value is greater than 0.05
- If the outcomes aren't coincidental
- Presuming that any difference between the actual and expected results is purely coincidental
- Assuming a normal distribution curve for the data
Hint:
Presuming that any difference between the actual and expected results is purely coincidental
The correct answer is: Presuming that any difference between the actual and expected results is purely coincidental
The hypothesis states that there is no significant difference between specified populations, any observed difference being due to sampling or experimental error.
A null hypothesis is a type of statistical hypothesis that proposes that no statistical significance exists in a set of given observations. Hypothesis testing is used to assess the credibility of a hypothesis by using sample data. Sometimes referred to simply as the "null," it is represented as H0.
