Question

In a recent study on gender differences in education, a sample of 7 boys had a mean score of 18.5 and a standard deviation of 4.1 on a Standardized Math Test. A sample of 11 girls had a mean score of 19.9 and a standard deviation of 3.6 on the same test. What is the t-statistic for this data? (Use the sample of boys as Group 1.)

Answer 1

Try a two-sample independent groups t-test. Use the data below to calculate your t-statistic.

Group 1 (Boys)
n = 7
mean = 18.5
sd = 4.1

Group 2 (Girls)
n = 11
mean = 19.9
sd = 3.6

I'll let you take it from here.
