WebStatistics is essential for achieving all of those goals, and this course will teach you the methods you need to make the most of your data. You'll gain hands-on experience designing experiments and framing questions for statistical analysis. You'll also expand your statistics toolkit to include a suite of powerful hypothesis tests. WebTo find this value, we need the significance level (α = 0.05) and the degrees of freedom. The degrees of freedom (df) are based on the sample sizes of the two groups. For the body fat data, this is: $ df = n_1 + n_2 - 2 = 10 + 13 - 2 = 21 $ The t value with α = 0.05 and 21 degrees of freedom is 2.080.
