What is the purpose of calculating the test statistic in hypothesis testing and how does it relate to the null hypothesis?
The test statistic assesses how consistent the sample data are with the null hypothesis and as it becomes more extreme, it indicates a larger difference between the sample data and the null hypothesis.
Why is it important to specify the characteristics of the test statistic's sampling distribution when finding the p value?
Why is it important to specify the characteristics of the test statistic's sampling distribution when finding the p value?
Sampling distributions provide context for the test statistic and allow for the calculation of probabilities related to its extremeness, which is necessary to find the p value.
What are some factors to consider when choosing the correct test statistic in hypothesis testing?
What are some factors to consider when choosing the correct test statistic in hypothesis testing?
The type of data being analyzed and the method of analysis are important factors to consider when choosing the correct test statistic.
