Intermediаte Stаtistics Lаb Exam 1 Instructiоns (Instructiоns are alsо available as a word document: Exam 1 Stats Lab.docx Download the two exam data sets (‘gradgre.sav’ and ‘childsleep.sav’). Complete the exam entirely in the SPSS output viewer. Once completed, you may either (1) save the output file as a .SPV or export the SPSS output as ‘lastname_firstname_Exam1.pdf’ Check the .SPV file or PDF to make sure that all of your answers are there Upload the file here. Use the data set “gradgre.sav” on Canvas to answer the first three questions. It has been collected from a group of graduate students, and includes their GPA, their performance on the GRE, and faculty ratings given to them over two semesters (fr1, fr2). (1) Using the compute procedure, create a new variable representing the MEAN of variables fr1 and f2. Call the new variable avgfr (for average faculty rating). Create a histogram for the variable. (5 pts.) (2) Examine whether the variable Total GRE (GREtotal) has any outlier scores. If so, report the a) Case number and b) GRE score. If you found no outliers, say so. (5 pts.) (3a) Now, select cases of participants whose GPA is greater than 3.00. (5 pts.) (3b) After you have selected cases of GPA greater than 3.00, find the descriptive statistics for the variable GPA. Include the mean, median, mode, standard deviation, variance, minimum, and maximum. (6 pts.) ~~~ Insert text into your SPSS output to answer the following two questions: (4) A researcher measures hours of sleep as a variable in her study. Is hours of sleep a nominal, ordinal, or scale variable measure? (5 pts.) (5) A sample of 22 fifth grade students has a grade point average of 3.0 in math. We know that the grade point average of all fifth grade students over the last five years is 2.75. We are interested in whether the grade point average of the 22 students is significantly different from the 2.75 GPA. What statistical test should be used to answer this research question? (5 pts.) ~~~ Use the data set childsleep.sav to answer the final two questions. A previous national sleep study of children in the United States found that the average child in the United States sleeps 8 hours a night (μ =8). A researcher at Florida Atlantic University collected data from 25 primary school children attending a local public school. This researcher is interested in whether the primary school children in this sample sleep less than the average child in the United States (μ =8). (6a) State the Null (H0) and Alternative (HA) Hypotheses as complete sentences below (using one complete sentence for each hypothesis). (6 pts.) (6b) Perform a One-Sample t-test in SPSS to evaluate whether the primary school children in this sample sleep less than the average child in the United States (μ =8). (6 pts.) (7) Report results in APA format, including the type of the test used, what you were evaluating, whether results were significant (with df, t- and p- values), and what you can conclude from the results. (7 pts.) A _________________ was performed to test the hypothesis _______________________ ________________. The results were __________________ , t(xx) = x.xx, p = .xxx. The average hours of sleep in this sample (M = XX.XX, SD = XX.XX) was ____________________________________________.
