the college offers all students an optional seminar on note taking and study skills. suppose that a researcher compares personality scores for students who elected to take the seminar with the scores for students who did not. identify the quasi independent variable and the dependent variable for the study.
The quasi independent variable is personality. The dependent variable is seminar participation interest.

3. Suppose a random sample of 300 U.S. college students was obtained and the average number of hours of sleep per night for each individual was determined. It was then determined that those students who averaged at least 7 hours of sleep per night had a higher cumulative gpa, on average, than those who did not Define the following: (a) The population(s) of interest.(The independent variables) (b) The variable measured.(The dependent variable). Is this an observational study or experiment? (c)...
Complete: Chapter 1 Problem Set 4. Dependent and independent variables Aa The following research studies consist of two or more groups of scores being compared. For each, decide whether the study is experimental or nonexperimental, and then identify the dependent, independent, or quasi-independent variables. A researcher would like to find out more about the determinants of college achievement. He conducts a study on 437 college students in which he measures their IQ levels and their grades in college courses. The...
A researcher is interested in the relationship between students’ participation in tutorials and academic achievement. She states the following hypothesis in the description of her study: Students who participate in tutorials that emphasise critical thinking skills will score higher on measures od academic achievement and self-esteem than students who participate tutorials that emphasise rote memorisation. Identify the variables in this study. What would be good names for the variables? Identify the independent variable(s) and dependent variable(s). Describe how each variable...
If a study was done that asked college students exactly how many A’s they have obtained (e.g., 0, 1, 2, etc.), the researcher is using: A nominal measure An ordinal measure An interval measure A ratio measure Provide an example of each of these two scales (ordinal and interval/ratio) that represent students’ performance in a statistics course. You found that a zero is included in a scale of a measurement. Which of the following is correct about the measurement scale?...
DQuestion 11 2 pts Merritt College conducted a study to determine if concentration levels of students who are working full-time affected grade point average. Students had to take a concentration test and completed a survey that determined student's concentration levels. Note: In this study, there is no zero concentration level or 100% concentration level. The experimenters determined that students who have a high concentration level" had higher grade point averages than those students with a "low concentration level" What is...
QUESTION 1 College students Suppose a recent study of 1,000 college students in the U.S. found that 8% of them do not use Facebook. Which of the following describes the population for this example? 1. All college students in the U.S. 2. The 1,000 college students who participated in the study, 3. All college students in the U.S. who do not use Facebook 4. The 8% of college students who do not use Facebook. QUESTION 2 Suppose you want to...
Almost all medical schools in the United States require students to take the Medical College Admission Test (MCAT). To estimate the mean score μ of those who took the MCAT on your campus, you will obtain the scores of an SRS of students. The scores follow a Normal distribution, and from published information you know that the standard deviation is 10.8 . Suppose that, unknown to you, the mean score of those taking the MCAT on your campus is 495...
5. Suppose a rehabilitation psychologist has developed a new job skills training program for people who have not been able to hold a job. Of the 14 people who agree to be in the study, the researcher randomly picks seven of these volunteers to be in a experimental group who will go through the special training program. The other seven volunteers are put in a control group who will go through an ordinary job skills training program. After finishing the...
2. Suppose that a random sample of 41 state college students is asked to measure the length of their right foot in centimeters. A 90% confidence interval for the mean foot length for students at this university turns out to be (21.709, 25.091). If we now calculated a 95% confidence interval, would the new confidence interval be wider than or narrower than or the same as the original? b. Suppose two researchers want to estimate the proportion of American college...
