YouTipExecuting the above code outputs the following result:
Welch Two Sample t-test
data: method_a and method_b
t = 4.4029, df = 17.764, p-value = 0.0003513
alternative hypothesis: true difference in means is not equal to 0
95 percent confidence interval:
4.640839 13.159161
sample estimates:
mean of x mean of y
84.0 75.1
From the results, we can see that the p-value is far less than 0.05, indicating that there is a significant difference in the scores between the two teaching methods.
