Question

A teacher expects that students will

perform better on a geography exam if
it is printed on pink paper rather than
white paper. Half of the students
receive the exam on pink paper, and
the other half on white, and then the
average exam score between the two
groups are compared. Which statistical
test would be most appropriate for this
scenario?
correlation (one-tail, positive)
correlation (one-tail, negative)
correlation (two-tail)
ANOVA (F-test)
O
paired/dependent t-test (one-tail)
O paired/dependent t-test (two-tail)
independent t-test (one-tail)
O independent t-test (two-tail)

Answer 1

The most appropriate statistical test for this scenario is the independent t-test (two-tail), which compares the means of two independent groups.

Step-by-step explanation:

The most appropriate statistical test for this scenario would be the independent t-test (two-tail).

The independent t-test is used to compare the means of two independent groups. In this case, the two groups are the students who receive the exam on pink paper and the students who receive it on white paper. By comparing the average exam scores between the two groups, the independent t-test can determine if there is a statistically significant difference in performance.

The two-tail option is chosen because we are interested in whether there is any difference in performance, regardless of the direction. The test will provide a p-value that indicates the likelihood of obtaining the observed difference in means by chance.
