What Does A Significant T Test Mean

What Does A Significant T Test Mean - The t test tells you how significant the differences between group means are. It lets you know if those differences in means could have happened by chance. The t test is usually used when data sets follow a normal distribution. What is Statistical Significance The terms significance level or level of significance refer to the likelihood that the random sample you choose for example test scores is not representative of the population The lower the significance level the more confident you can be in replicating your results

We ll use a two sample t test to evaluate if the difference between the two group means is statistically significant The t test output is below In the output you can see that the treatment group Sample 1 has a mean of 109 while the control group s Sample 2 average is 100

T-tests are statistical hypothesis tests that you use to analyze one or two sample means. Depending on the t-test that you use, you can compare a sample mean to a hypothesized value, the means of two independent samples, or the difference between paired samples.
