Over the years, students and teachers have developed a variety ofstrategies to help prepare for an upcoming test. But how do you knowwhich strategy is best? A partial answer to this question comes from aresearch study comparing three different strategies (Weinstein,McDermott, & Roediger, 2010). In the study, students read a passageknowing that they would be tested on the material. In one condition,participants simply reread the material to be tested. In a secondcondition, the students answered prepared comprehension questionsabout the material, and in a third condition, the students generatedand answered their own questions. The data in Table (problem 2 table)show the pattern of results obtained in the Weinstein et al. (2010)study.

Does the shape or color of a pain pill influence its effectiveness? Although logically it shouldn’t, whether we believe a drug will work does have a powerful effect on our perceptions (e.g., placebo effect). In this experiment, 4 groups of adult patients were given the same amount of Advil after dental surgery for pain relief, but the color and shape of the pill varied. Researchers hypothesized that an unusual shape or color would lead people to believe the pills were new and special and thus would expect them to be more effective than common round, white pills. Researchers also wanted to know if there is an interaction between shape and color what is the purpose and design of the study as well as the characteristics of the participants in the sample?
If a researcher concludes that worker productivity increased when playing upbeat music but was incorrect, which of the following best represents her conclusion? Group of answer choices: correct decision Type III error Type II error Type I error
12)A crossover trial is a type of experiment used to compare two drugs. Subjects take one drug for a period of time, then switch to the other. The responses of the subjects are then compared using matched-pair methods. In an experiment to compare two pain relievers, seven subjects took one pain reliever for two weeks, then switched to the other. They rated their pain level from 1 to 10, with larger numbers representing higher levels of pain. The results are listed below. Can you conclude that the mean pain level is more with drug B? Use the 0.05 level and the P-value method. Subject 1 2 3 5 3 4 5 6 7 2 5 2 6 Drug A 1 1 Drug B 3 7 (c) State the appropriate null and alternate hypotheses. (d) Compute the P-value. e) State a conclusion. 6 5 6 6 (c) Determine whether to reject Null Hypothesis. 13
The Bureau of Labor Statistics reports that the official unemployment rate for Black people was 10.4% and 4.7% for White people in February 2015. Select all correct answers for this question. O The samples of white and black people are independent. The explanatory variable is the unemployment rate. The response variable is the unemployment rate. The response variable is race.
Work this problem involving a true/false and multiple choice test. Assume that the test has 7 true/false questions, and 11 muiltiple choice questions (3 options per questions), each with exactly one correct answer. If a student guesses randomly on each question, what is her expected score?
Dr. Moo conducted a research project in which she compared the impact of two types of therapy (pizza therapy and chocolate therapy) and gender on college students’ happiness. How many null hypotheses did she have, and how would you write them?
Suppose a researcher is trying to understand what makes living in a particular city desirable. She uses a list from a popular magazine of the current top 50 desirable cities to live in. Each city was given a desirability score by the magazine's viewers. The researcher is curious about how well she can predict those scores using only two independent variables: the number of miles to the closest airport and the median home price. She obtains the values for number of miles to the closest airport and median home price for each of the 50 cities and calculates the following values: Zero-Order Correlations: # of Miles to the Closest Airport and Median Home Price City Desirability Rating # of Miles to the Closest Airport Median Home Price City Desirability Rating 1.0001.000 −0.447−0.447 0.6040.604 # of Miles to the Closest Airport 1.0001.000 −0.066−0.066 Median Home Price 1.000 The researcher computes the partial correlation of 0.6440.644 between the city…
A campus researcher wanted to investigate the factors that affect visitor travel time in a complex, multilevel building on campus. Specifically, he wanted to determine whether different building signs (building maps versus wall signage) affect the total amount of time visitors require to reach their destination and whether that time depends on whether the starting location is inside or outside the building. Three subjects were assigned to each of the combinations of signs and starting locations, and travel time in seconds from beginning to destination was recorded. How should the data be analyzed? Wall Signs Map Starting Room Interior 141, 119, 238 85, 94, 126 Randomized block design O Completely randomized design 2 x 2 factorial design Levene's test Exterior 224, 339, 139 226, 129, 130
A social and personality psychologist thinks that creativity differs by personality traits, rather than the traditional view that it is a cognitive process. Specifically, this psychologist thinks that introverts are more creative than extraverts. The researcher gives a personality test to a group of 16 university students and then separates them based on the assessment results into 2 groups: the extraverts and the introverts. The participants are then asked to write a short story which is rated on creativity by a well-known author. The creativity scores range from 0 to 20 on an interval scale, where higher scores indicate greater creativity. The results are shown in Table 2. Using the 0.05 alpha level, are introverts more creative than extroverts? Use all of the steps of hypothesis testing. extrovert introvert 8 18 7 17 11 10 3 14 5 16 8 15 7 19 4 12
Suppose you are the manager of two beachfront hotels : The Palms and Golden Sands. You'd like to know if there is a difference in guest satisfaction between the two hotels. To investigate this, you conduct a survey and ask guests upon departure if they are likely to return to the hotel in the future. For The Palms, 163 out of 227 guests who were surveyed responded " yes ". For Golden Sands, 154 out of 262 guests responded "yes ". Answer the following questions. Round any numbers in your final answers to 2 decimals. 1) Calculate a 95 % confidence interval for the difference in satisfaction rates between The Palms and Golden Sands (Show work) 2) Use the critical value approach to test, at a 1% significance level, whether or not the guest satisfaction rates are different between the two hotels. What do you conclude ? (In your answer, show the steps involved with testing) 3) What is the p-value of your test in part 2?
For one month, 500 elementary students kept a daily record of the hours they spent watching television. The average number of hours per week spent watching television was 28. The researchers conducting the study also obtained report cards for each of the students. They found that the students who did well in school tended to spend less time watching television than those students who did poorly. Listed are several possible statements concerning the results of this research. Place a check by every statement that you agree with based on this study. a. Even though students who did well watched less television, this doesn't necessarily mean that watching television hurts school performance. b. One month is not a long enough period of time to estimate how many hours the students really spend watching television. c. The sample of 500 is too small to permit drawing conclusions about elementary students in general. d. I don't agree with any of these statements. e. If a student decreased the…
Verbal intelligence was a topic that Jamie was very interested in. She conducted a study to see whether children with ADHD had lower scores on measures of verbal intelligence than those without ADHD. She divided children in her study into 4 groups- those clearly diagnosed with ADHD- combined type, those clearly diagnosed with ADHD- inattentive type, those with ADHD symptoms but not clearly diagnosed, and those without ADHD. Then she measured their scores on the Reading Comprehension task, Vocabulary task and Writing Task. What type of statistic did she run? A 4 way MANOVA A 4 way MANCOVA A one way MANOVA A Factorial MANOVA
