The test given to each participant will involve reading 4   short passages measuring 350   words in length and followed by answering 10   multiple choice questions then 10   true or false questions. The scores of both the multiple choice and true or false test will be evaluated and then compared to determine the impact of noise type on reading comprehension. A t - test will be used to compare the reading comprehension scores between the two conditions and analyze participant accuracy on the comprehension test. If the result is statistically significant, it will support the hypothesis that steady state background noise results in higher reading comprehension scores compared to intermittent background noise. what would the data analysis be for this?
