A psychology professor wants to know whether confidence in memory skills is related to memory quality in current first year students at his small college.
00:11
That is, the goal of the study is to find the relationship between confidence in memory skills to memory quality, where the participants are first year college students.
00:22
These participants complete an online memory task in which, first they are shown a list of 60 words.
00:30
Next, they are shown a list that includes five new words that are completely unrelated to the words on the original list.
00:38
Then they are asked to identify the words on the second list that appeared on the original list.
00:44
The professor describes the measure of memory quality as the percentage of new unrelated words that were mistakenly thought to be on the original list.

He also asked the students to report several characteristics such as, their age, gender, and a self -assessment of their memory skills.

The professor chooses 100 students at random to complete the memory task and observes that the average percentage of words that were correctly recognized on the original list was 68.
01:31
The professor infers that if all 1 ,000 students had completed the study, the results would show that an average of 68 % with some sampling error of the words were correctly recognized being on the original list.
