The test statistic is a numerical quantity computed from the data of a sample and is used in hypothesis testing to determine the likelihood of the null hypothesis being true. It is compared to a critical value or p-value to make a decision on whether or not to reject the null hypothesis. The significance level is the threshold for rejecting the null hypothesis, and a parameter is a characteristic of a population, not a sample.
