6.1.
Imagine that you had to gather a random sample of the student body at your school. How would you acquire a list of the population? Would the list be complete and accurate? What procedure would you follow in selecting cases? Would cluster sampling be an appropriate technique (assuming that no list was available)? Describe in detail how you would construct a cluster sample. (HINT: See the One Step at a Time box in this chapter.)

Ch. 2 A _____________ is a summary display for a distribution of data organized

Ch. 2
A _____________ is a summary display for a distribution of data organized or summarized in terms of how often (or frequently) scores occur.
Ch. 3
A scientist records the following sample of scores (n = 6): 3, 6, 4, 1, 10, and 12. What is the sample mean of these scores?
Ch. 4
A researcher measures the following scores: 12, 14, 16, 18, and 20. Compute the SS for these data.
Ch. 8
State the four steps of hypothesis testing.
The decision in hypothesis testing is to retain or reject which hypothesis: null or alternative?
Ch. 9
Assuming α = .05, what is the critical value in each of the following t distributions?
df = 10, two-tailed test
df = 30, one-tailed test (lower tail critical)
df = ∞, two-tailed test
df = 15, one-tailed test (upper tail critical)
A researcher reports that a sample of workers with high-stress careers slept significantly less than workers in the general population, t(48) = 2.36, p < .05. Compute eta-squared for this one-sample t test.
Ch. 10
A researcher records the amount of computer use (in hours per day) in a sample of students and then matches the students based on their amount of computer use. Is this an example of matching through experimental manipulation or matching through natural occurrence?
Ch. 12
State the four assumptions for the one-way between-subjects ANOVA.
Make a decision given the following values for the F statistic in a test with 3 and 20 degrees of freedom.
Fobt = 3.05
Fobt = 4.00
Fobt = 5.35
Social comparisons and prosocial behavior. To check that a manipulation of social comparison made in the study was effective, Yip and Kelly (2013) computed a one-way ANOVA and reported the following result for one such check: F(2, 120) = 6.42. Following on the information given, answer the following questions.
How many groups were compared in this test?
How many participants were observed in this study?
Was the outcome of this test significant at a .05 level of significance?
Ch. 13
How are participants observed using the within-subjects design?
State the three sources of variation in the one-way within-subjects ANOVA.
Ch. 14
If the value of mean square error increases, will the value of the test statistic increase or decrease?
Rodent species and sociality. Freitas, El-Hani, and da Rocha (2008) tested the hypothesis that rodent species (four different species) and sex (male, female) influence the level of affiliation acquired through social behavior. They measured the number of social behaviors exhibited by each rodent during a social encounter. As part of their study, they reported the following:
Hypothesis test was performed by means of a [factorial] two-way ANOVA. The test was able to detect significant differences only among species, not among sexes. (Freitas et al., 2008, p. 389)
Is a significant main effect or interaction evident in this study and, if so, for which factor?
What is the appropriate next step?
Ch. 15
A researcher reports a significant positive correlation and concludes that spending more time writing a research paper will cause a better grade on the paper. Is this conclusion appropriate? Explain.
How can an outlier alter the relationship between two factors?
Ch. 16
What is a key advantage of using multiple regression?

This lab will have you practice some of the skills we’ve learned from this week

This lab will have you practice some of the skills we’ve learned from this week and the previous week in SPSS. We’ll be calculating different descriptive statistics, the z-score, and percentile rank. Additionally, we’ll practice recoding variables in SPSS which we will continue to do in future labs when we cover more complex inferential statistics.

Mini- Study Part I In this course you will conduct a mini study. You will survey

Mini- Study Part I
In this course you will conduct a mini study. You will survey 50 people through any method you choose to find out information on your topic. You will then calculate the statistics for your data. It is important to remember your mini study should use quantitative values since this is a statistics course so you can complete the required calculations. When you pick a topic, make sure it is something people are comfortable answering and that you only use adults. Complete this worksheet and then begin your survey once it is graded so that you can write up your results in Module 7.
Item Description
1 State your topic
2 Who is the population for your claim? Justify your statement.
3 What question(s) will you ask in your survey to gather data on your claim? Explain the rationale for each question.
4 What variables will be in your study? What type of variable are they (ordinal, nominal, discrete, continuous, etc)?
5 Where will you post your survey and how will it reach your target population? (Facebook, email, in person, etc)
6 How will you collect your data? (Survey Monkey, Facebook Question, By hand/Excel, etc)
7 What type of sampling method will you use? Justify your choice and cite a reference supporting your decision.
8 What 2 types of graphs that you have learned about are the most appropriate for your data? Justify your statement and cite a reference supporting your decision.
*Hint: think about if your data may have outliers, is quantitative, is categorical vs interval, etc.
9 What 8 descriptive statistics that you have learned about are the most appropriate for your data? Justify your statement and cite a reference supporting your decision. *Hint: think about if the data has outliers, is quantitative, is categorical vs interval, etc. *Note: if you have more than one survey question you can count statistics on EACH*
