Question:
In a hypothetical study, you recruited 30 participants to play a simple video game in which they had to press a button every time they heard a particular word in order to blow up a balloon. In Game A, the game had quiet 8-bit music, similar to Tetris or the original Mario Brothers games. In Game B, the game had background noise that included voices, similar to being in a busy coffee shop. You are curious if there is any relationship between performance in quiet, nonverbal settings and performance in noisy settings with other talkers.
For each game, calculate the mean, median, mode, range, variance, and standard deviation. Finally, calculate the correlation between the two games. Is it positive or negative? Strong, moderate, or weak?
