Question

A study was conducted to determine if students remembered more medical terms from an on-line or in -person course. The average number of terms recalled by a sample of 10 students in the inperson course was 75 with a standard deviation of 2.0. The average number of terms recalled by a sample of 10 students in the on-line course was 50 with a standard deviation of 3.5. What statistical inference tool should be used to determine if the difference between the two groups is statistically significant ? A. chi-squared test B. ANOVA C. two-sample t-test D. Regression

Explanation / Answer

Since it is to be determined which course is better "on-line" or "in-person", so we have to compare their means

and to compare the means the "two-sample t-test" statistical inference is used.

Hence the correct option is C. two-sample t-test
