Participants threw 20 darts at a target that was behind a screen. They could not see the target. In one condition, after they threw each dart, they were told how far away they were and whether the dart was too far to the left, right, above or below; in the other condition, they simply threw the darts with no feedback. All subjects performed in both conditions. Their scores are shown below. What type of test should be used for this analysis?

Solution

The scores are not displayed in the question.

Anyway, when there is a common subject to 2 samples of data, we use a Paired t-test.

As the participants form the common subject, while recording data in both situations, we compare the results in both situations for each and every subject and record the deviation.

Similarly, deviations for all subjects are recorded and tested if they differ from a hypothesized value (like zero).
