What is an example of the professor using descriptive statistics?
A. She infers that if all 500 students had done the experiement, the results would show that an average of 34% (plus or minus sampling error) of new words were mistakenly identified as original words because they were conceptually similar.
B. She reports that the average percentage of new but conceptually similar words that were mistakenly thought to be on the original list was 34%
C. She randomly chooses the 50 students to represent the 500 volunteers.

What is an example of the professor using inferential statistics?
A. She characterizes the first-year students at the college as consisting of 268 males and 232 females
B. She infers that if all 500 students had done the experiment, the results would show that an average of 34% (plus or minus sampling error) of new words were mistakenly identified as original words because they were conceptually similar.
C. She reports that the average percentage of new but conceptually similiar words that were mistakenly thought to be on the original list was 34%

A psychology professor wants to know whether study skills are related to memory quality in current first-year students at her small college. Participants in the study (first-year students at her college) complete an online memory task. The students are first shown a list of 60 words. Next they are shown a list of five new words that are conceptually similar to words on the original list. Then they are asked to identify the words on the second list that appeared on the original list. She uses the percentage of new but conceptually similar words that were mistakenly thought to be on the original list as her measure of memory quality. She also asks the students to report several characteristics such as their age, their gender, and a self-assessment of their study skills Each of the 500 first-year students (268 males and 232 females) at her school volunteers to participate. The professor chose 50 students at random to complete the memory task and answer the questions. The average percentage of new but conceptually similar words that were mistakenly thought to be on the original list was 34% The professor infers that if all 500 first-year students had completed the study, the results would show that an average of 34% (plus or minus sampling error) of new words were mistakenly identified as original words because they were conceptually similar
