Chapter 7, Problem 5E
A researcher would like to compare two methods for teaching math to third-grade students. Two third-grade classes are obtained for the study. Mr. Jones teaches one class using method A. and Mrs. Smith teaches the other class using method B. At the end of the year, the students from the method-B class have significantly higher scores on a mathematics achievement test. Does this result indicate that method B causes higher scores than method A? Explain your answer, and identify the general problem that precludes a cause-and-effect explanation.

An athletic director proudly states that he has used the average GPAs of the university's sports teams and is
predicting a high graduation rate for the teams. Why is this method unsafe?
Choose the correct answer below.
OA. This method is unsafe because the average GPA may differ for each team. Using the average of the average
GPA of each team obscures the possibility that certain teams tend to perform less well in classes.
B. This method is unsafe because there is more variation in the GPAs of the athletes than the average GPA of
the university's sports teams. Strong students may offset weak students in calculating the average GPAS,
which makes it appear more likely that most students are doing well.
OC. This method is unsafe because it is dangerous to extrapolate into the future. Classes in university tend to
become more difficult, which makes it less likely that the average GPA will hold as time goes on.
D. This method is unsafe because there is a minimum GPA required to graduate. If…
Your math teacher Ms. Washington notices that students with calculators do better on her math tests than those without calculators. To test her hypothesis, she randomly chooses 20 students and tracks their progress. She then gives 10 of those students a calculator and after a period of times compares progress again. The calculator group showed an increase. Which fact would lead you to believe that the relationship between calculator and progress may be one of causation?
Tim’s scores decreased with the calculator.
Tom’s scores increased with the calculator.
A control group was used and the subjects were chosen randomly.
Tammy’s scores did not change with the calculator.
You've just completed a depleting, or mentally draining task. After doing so do you think you would perform better than, the same as, or worse than other participants on a new task that requires you to be creative if the task is described as hard (as compared to if that task is described as easy)?
In this experiment, participants in the control group (the non-depleted group) were given 4 minutes to write a short story about a place they had recently visited (a relatively easy task). A second group of participants (the depleted group) was given the same task but they were told not to use the letters "U" and "K" in the story-a mucher harder task.
After the first task, all participants were told that they would next participate in a study of creativity. They were told that while creativity sometimes arises through inspiration, it can also come about through perseverance. All participants were told that they should use perseverance to get through the creative task. The catch? Half of the…

Kentrex, a maker of game consoles, wants to determine whether a proposed new advertising campaign will change gamers' perception of the brand. To conduct the test, Kentrex selected a selected a panel of 6 game players and used an extensive questionnaire to measure brand perception before and after the panel is shown the new campaign through a series of ads. Using the before-and-after brand perception scores in the table below and assuming that the appropriate population conditions are satisfied, construct a hypothesis test of the null hypothesis that there is no difference in average before-and-after scores for the populations.

However, there may be another problem. It may be that watching television also reduces the amount of physical exercise, causing weight gains. A sample of 15 10-year-old children was taken. The number of pounds each child was overweight was recorded (a negative number indicates the child is underweight). In addition, the number of hours of television viewing per week was also recorded. These data are listed here.

One group has regular quizzes (n=4), one group has three large exams (n=4), and the third group only has a final exam (n=4).

State the null and all possible research hypotheses. Review the results below (I used SPSS) and answer the questions that follow. Scenario: A researcher wants to see if gender and / or income affects the total amount of help given to a stranger who is sitting on the side of a busy road with a sign asking for help. The independent variables are gender, income, and the interaction of gender and income. The dependent variable is total help. He wants to know if one or both factors – or the interaction of the two - affects the total amount of help offered. Because he is analyzing two independent variables (gender and income), he used a factorial ANOVA. His results show the main effect of each of the independent variables on the dependent variable (total help) and the interaction effect. The researcher is using a 95% confidence interval which means that he wants to be at least 95% sure that his independent variables…arrow_forward
- Below you will find a research scenarios. Your task is to identify the proposed analysis and why you chose that analysis for each of these scenarios. State the research question that aligns with the scenario and the analysis. Next run the appropriate analyses and report your findings in APA Research scenario 2: Historians are interested in the accuracy of eyewitness accounts of traumatic events. One study examined survivors' recall of the sinking of the ship Titanic (Riniolo, Koledin, Drakulic, & Payne, 2003). The researchers reviewed the transcripts of survivors' testimony at governmental hearings (www.titanicinquiry.org) to see whether they testified that the ship was intact or breaking apart during the ship's final plunge (it was in fact breaking apart). To test for eyewitness accuracy, testimony of 20 survivors was examined to see if there was an equal likelihood of survivors saying the ship was intact or breaking apart.

She randomly assigned her clients into two groups. She asked the first group to meditate every day for 15 minutes for 6 months in addition to their regular counseling sessions. In the second group, she continued her regular counseling sessions without any extra treatment. Since the psychologist does not know how to run the analysis, your task is, by using your statistics skills, to inform her whether the mindfulness practice has made a difference in the lives of her clients and in what sense. To provide her with an answer, I want you to run two different tests: An Independent Samples t-test and a One-Way ANOVA, report their results, and compare the findings of these two analyses.arrow_forwardLeRoy, a starting player for a major college basketball team, made only 40% of his free throws last season. During the summer, he worked on developing a softer shot in hopes of improving his free throw accuracy. In the first eight games of this season, LeRoy made 25 free throws in 40 attempts. You want to investigate whether LeRoy's work over the summer will result in a higher proportion of free-throw successes this season. What conclusion would you draw about LeRoy's free throw shooting?
