Question

A team of cognitive psychologists conducted a study on the effects of sleep deprivation on short-term memory decay. Forty-eight participants stayed in a lab for two days. Twenty-four of the participants were randomly assigned to a condition in which they were not permitted to sleep during that period. The other twenty-four were allowed to sleep whenever they wanted. At the end of the two days, the participants completed a task that involves reading a list of 20 words, then recalling as many words as possible. The appropriate statistical test is __________

Answer 1

An independent samples t-test is the appropriate statistical test to compare the short-term memory performance of two groups, one sleep-deprived and one allowed to sleep, in a study focused on sleep deprivation and memory decay.

Step-by-step explanation:

The appropriate statistical test for a study examining the effects of sleep deprivation on short-term memory decay would likely be an independent samples t-test. This test is used to compare the means of two groups that are independent of each other. In the study described, there are two conditions: a group that was deprived of sleep and a group that was allowed to sleep. After the two-day period, participants completed a task involving memory recall which would yield quantitative data suitable for a t-test to determine if there is a significant difference in short-term memory performance between the sleep-deprived group and the control group.

Answer 2

The appropriate statistical test is Memory methods

Step-by-step explanation:

In experimental work carried out by cognitive psychologists, there are various methods they could have adopted when carrying out their research works. some depend on the area of study and consist primarily of chronometric methods, memory methods, cross-population studies, case studies, measures of brain activity, and computational modeling.

For study on sleep deprivation on short term memory, the best statistical method to be used is the memory method
