You are going to analyze a study on the intellectual development of engineering students. Perry’s model of intellectual development was applied to undergraduate engineering students at Penn State (Journal of Engineering Education, Jan. 2005). Perry scores (ranging from 1 to 5) were determined for 21 students in a first-year, project-based design course. (Note: A Perry score of 1 indicates the lowest level of intellectual development, and a Perry score of 5 indicates the highest level.) The average Perry score for the 21 students was 3.27.
Identify the experimental units for this study.
What is the population of interest? The sample?
What type of data, quantitative or qualitative, are collected?
Use the sample information to make an inference about the population.
Use a random number generator to select 3 of the 21 students for further testing.
When an interaction term is statistically significant, you must be cautious in interpreting the main effects. True or False?

- What is an experiment?arrow_forwardWhat is an experiment? Give two examples.arrow_forwardIt is common for baseball pitchers to use stretching to prepare for a game. But does this make a difference? The authors of a paper on the effects of stretching in baseball carried out an experiment to compare two different types of stretching and a control treatment consisting of no stretching. Participants were adult males with varying levels of baseball throwing experience and who were not professional or collegiate baseball players. Participants in the two stretching treatments went through a warm-up that included 8 minutes of stretching. Each participant (all three groups) then threw 10 pitches, and the average speed (km/hour) was calculated. (a) Explain why it is important that the participants be assigned at random to the three different treatment groups (Stretching Method 1, Stretching Method 2, and No Stretching). Random assignment ensures that our experiment systematically favors one experimental condition over all others and attempts to create experimental groups that are as…arrow_forward

An employee survey was given to three groups: one group under a manager who started using a transformational motivation technique, one group under a manager who began using a transactional motivation technique, and then a control group with no new technique used. Stress levels were self-reported by the employees on 10-point Likert scales (0 – no stress, 1- little stress, 9 – very high stress). The results are shown below. Use alpha = 0.05. Transformational Transactional Control 0 2 6 7 5 5 3 3 8 5 0 9 2 1 5 Explain why using ANOVA is appropriate for this data. What assumptions need to be addressed to use this type of test?

- Have you heard of “pet therapy”? Access to a pet (typically, but not limited to, a dog) has been shown to be associated with beneficial physical responses like lowered blood pressure and reduced anxiety. In a review of the pet therapy literature, Giaquinto and Vlanetini (2009) describe a study that compared two groups of heart patients. Group 1 consisted of patients with high blood pressure and who owned pets. These participants were matched with participants in a control group who also had high blood pressure but did not own pets. Six months later, blood pressure was measured in both groups. Does having a pet reduce blood pressure? what statistical test should be used and why?arrow_forwardA two-factor study investigates the effects of self-esteem (low vs. high) and gender (males vs. females) on anxiety scores. The following data represents the means for each treatment condition. Low self-esteem High self-esteem Male 5 11 Female 10 3 The data shows that there is a self-esteem by gender interaction. Explain the self-esteem by gender interaction (include individual means in your explanation)arrow_forwardStressed-Out Bus Drivers. Previous studies have shown that urban bus drivers have an extremely stressful job, and a large proportion of drivers retire prematurely with disabilities due to occupational stress. In the paper, “Hassles on the Job: A Study of a Job Intervention With Urban Bus Drivers” (Journal of Organizational Behavior, Vol. 20, pp. 199–208), G. Evans et al. examined the effects of an intervention program to improve the conditions of urban bus drivers.Amongother variables, the researchers monitored diastolic blood pressure of bus drivers in downtown Stockholm, Sweden. The data, in millimeters of mercury (mm Hg), on the WeissStats site are based on the blood pressures obtained prior to intervention for the 41 bus drivers in the study. Use the technology of your choice to do the following. a. Obtain a normal probability plot, boxplot, histogram, and stemand-leaf diagram of the data. b. Based on your results from part (a), can you reasonably apply the one-mean t-test to the…arrow_forward
- A study is designed to test the effect of light level on exam performance of high school students. The researcher believes that light levels might have different effects depending on a person's grade in school (1st year, sophomore, junior, or senior), so wants to make sure all grades are equally represented in each treatment. The treatments are fluorescent overhead lighting, yellow overhead lighting, no overhead lighting (only desk lamps). (a) Identify these variables.arrow_forwardDoes posting calorie content for menu items affect people’s choices in fast-food restaurants? According to results obtained by Elbel, Gyamfi, and Kersh (2011), the answer is no. The researchers monitored the calorie content of food purchases for children and adolescents in four large fast-food chains before and after mandatory labeling began in New York City. Although most of the adolescents reported noticing the calorie labels, apparently the labels had no effect on their choices. Data similar to the results obtained show an average of M =786 per meal with s = 85 for n =100 children and adolescents before the labeling, compared to an average M = 772of with s =91 for a similar sample of n = 100 after the mandatory posting. Use a two-tailed test with alpha = .05 to determine whether the mean number of calories after the posting is significantly different than before calorie content was posted.arrow_forwardDoes posting calorie content for menu items affect people’s choices in fast food restaurants?
