What does the numerator of the z score test statistic measure?

The numerator of the z-score test statistic measures the points earned on the test. The denominator measures the amount of possible points that could have been earned.


What is test statistic. Why do you have to know the distribution of a test statistic?

A test statistic is used to test whether a hypothesis that you have about the underlying distribution of your data is correct or not. The test statistic could be the mean, the variance, the maximum or anything else derived from the observed data. When you know the distribution of the test statistic (under the hypothesis that you want to test) you can find out how probable it was that your test statistic had the value it did have. If this probability is very small, then you reject the hypothesis. The test statistic should be chosen so that under one hypothesis it has one outcome and under the is a summary measure based on the data. It could be the mean, the maximum, the variance or any other statistic. You use a test statistic when you are testing between two hypothesis and the test statistic is one You might think of the test statistic as a single number that summarizes the sample data. Some common test statistics are z-score and t-scores.

Example of the difference between a parameter and a statistic?

perameter is a measure of population or universe, statistic is a measure of a sample data drawn from population


What is the conclusion if the test statistic is the same as the critical value?

Any decision based on the test statistic is marginal in such a case. It is important to remember that the test statistic is derived on the basis of the null hypothesis and does not make use of the distribution under the alternative hypothesis.
