T- table statistics

WebThe T distribution (also called Student’s T Distribution) is a family of distributions that look almost identical to the normal distribution curve, only a bit shorter and fatter. The t distribution is used instead of the normal distribution when you have small samples (for more on this, see: t-score vs. z-score).The larger the sample size, the more the t … WebThe sample size . Usually in stats, you don’t know anything about a population, so instead of a Z score you use a T Test with a T Statistic. The major difference between using a Z score and a T statistic is that you have to estimate the population standard deviation. The T test is also used if you have a small sample size (less than 30).

WebAn easy way to handle that is to adjust the p value threshold by dividing them by the number of tests (in this case 25). The more precise formula is: Adjusted p value = 1 - (1 - p value)^ (1/n). However, the two different formulas derive almost the same adjusted p value. There is another major issue with your hypothesis testing exercise.
