Identifying populations, samples, statistics, parameters, and variables AaAa A psychology professor wants to know whether verbal ability is 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 that includes five new words that are completely unrelated 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 unrelated 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, gender, and verbal SAT score. Each of the 1,000 first-year students (543 males and 457 females) at her school volunteers to participate. The professor chose 100 students at random to complete the memory task and answer the questions. The average percentage of new unrelated words that were mistakenly thought to be on the original list was 12%. The professor infers that if all 1,000 first-year students had completed the study, the results would show that an average of 12% (plus or minus sampling error) of new words were mistakenly identified as original words despite being completely unrelated to the words on the original list. Which of the following are variables in the study? Check all that apply The 100 students The 1,000 students The students' verbal SAT scores The students' percentage of new unrelated words that were mistakenly thought to be on the original list 5:36 PM 9/18/2017 here toExplanation / Answer
There are two variables in the above experiment. An experiment is carried out to observe the cause and effect relationship of independent variable on the dependent variable.
The independent variable in the above study is, the students' percentage of unrelated words that were mistakenly thought to be on the original list. The experimenter manipulated the independent variable to see whether it affects the students' verbal SAT scores which is the dependent variable.
The study above is to see whether verbal quality is related to memory quality.
Thus, the correct multiple answers are option C and D.
The population in the above study is the 1,000 first year students at the college and the sample in the study is 100 students. A sample is any number of individuals taken from the population for the purpose of research analysis. A sample is considered to be the true representation of a population.
Thus, the correct answer is, D.
