Assuming that a researcher hopes to demonstrate that a treatment or group membership variable makes a significant difference in outcomes, which term does the researcher hope will be larger: MSbetween or MSwithin?
This occurs when there are two potential variables that could have caused the outcome and it is not possible to determine which actually cause the results. A) systematic B) confounding C) convenience D) sampling
2.1 The Australian Bureau of Statistics (ABS) has recently released a report on the relationship between international students’ ethnicity and enrolments in higher education. Identify the dependent variable(s) and the independent variable (s) in the above scenario.
The head of the quality control department at a printing company would like to carry out an experiment to determine which of three different glues results in the greatest binding strength. Although they are not of interest in the current investigation, other factors thought to affect binding strength are the number of pages in the book and whether the book is being bound as a paperback or a hardback.a. What is the response variable in this experiment?b. What explanatory variable will determine the experimental conditions?c. What two extraneous variables are mentioned in the problem description? Arethere other extraneous variables that should be considered?
If gender is the independent variable of a quasi-experiment, this experiment must have a between-subject design. Group of answer choices True False
A manufacturer is considering purchasing parts from three different suppliers. The parts received from the suppliers are classified as having a minor defect, having a major defect, or being good. Test results from samples of parts received from each of the three suppliers are shown below. Note that any test with these data is no longer a test of proportions for the three supplier populations because the categorical response variable has three outcomes: minor defect, major defect, and good.
Suppose an observational study is said to be a case-control study. Which of the following is true? (1 answer) A.) The study observes facts from the present, or over a very short period of time. B.)The study attempts to control different levels of a variable, called factors, comparing results to a control group. C.) The study observes facts from the past, or accesses previous records. D.) The study observes characteristics of individuals over a long period of time, perhaps not concluding until many years from now.
A researcher is interested in the impact of joining a weight loss program in the past 12 months on the individual’s weight loss. The analysis was restricted to people aged 16 and older who answered yes to the question “During the past 12 months, have you tried to lose weight?” About 5% of the sample had joined a weight loss program in the past year. (i) Why do we restrict our analysis to those who answered yes to this question? (ii) Below is a subset of some of the other variables included in the survey. Questions were asked about actions taken in the past 12 months. Which ones do you believe should be included as covariates? Provide a justification for your choice. Age BMI Gender Height Average minutes of exercise per week. Whether they tried to eat less calories. Whether they tried to eat less fat. Whether they tried to eat less carbs. (iii)The researcher has decided to use Propensity Score Analysis. What would be the appropriate estimator for this analysis: Average Treatment…
7) The following results are from data that were collected from a sample of Chicago Cubs baseball games. The dependent variable is ATTENDANCE, TEMP is a variable measuring the forecasted game-time temperature: WIN% is a variable measuring the winning percentage of the Cubs before the game is played, OPWIN% is a variable measuring the winning percentage of their opponent, WEEKEND is a dummy variable = 1 if the game is played on a weekend and = 0 if the game is played during a weekday, PROMOTION is a dummy variable = 1 if there is a promotion for the game (giving away something to those who attend the game) and = 0 if there is not a promotion, and WEEK*PROM is an interaction term equal to WEEKEND*PROMOTION. a) What is the predicted attendance if TEMP = 70, WIN% = 500, OPWIN% = 500, the game is played on a weekend and there is NO promotion? b) What is the predicted attendance if TEMP = 70, WIN% = 500, OPWIN% = 500, the game is played on a weekend and there is a promotion? c) Based on…

A study that tells us whether two variables are associated, but does not tell us if one variable causes or influences the other, is: Question 2 options: A) a n experimental study without a control group. B) a descriptive study. C) a correlational study. D) an experimental study with one or more control groups.
It appears that there is some truth to the old adage “That which doesn’t kill us makes us stronger.” Seery, Holman, and Silver (2010) found that individuals with some history of adversity report better mental health and higher well-being compared to people with little or no history of adversity. In an attempt to examine this phenomenon, a researcher surveys a group of college students to determine the negative life events that they experienced in the past 5 years and their current feeling of well-being. For n = 18 participants with 2 or fewer negative experiences, the average well-being score is M = 42 with SS = 398, and for n = 16 participants with 5 to 10 negative experiences the average score is M = 48.6 with SS = 370. a.) Is there a significant difference between the two populations represented by these two samples? Include whether you reject or retain the Null Hypothesis. Use a two-tailed test with α = 0.01 b.) Compute Cohen’s d to measure the size of the effect. c.) Write a…
