Comparing Means Worksheet
eight-item algebra test. Each item describes a problem and presents four possible answers to the problem. The scores on each item are 1 or 0, where 1 indicates a correct response and 0 indicates a wrong response. The IBM® SPSS® data file contains six cases, each with eight item scores for the algebra test. Conduct a one-sample t-test on the total scores. On the output, identify the following: TASK ONE: PLACE OUTPUT HERE TASK TWO: ANSWER THESE QUESTIONS a. Mean algebra score b. T value c. P value 2. Review the one-way ANOVA instructional video before completing this problem. The data set for this problem can be found through the Pearson Materials in the Textbook Resources link. The data for this question is in the data file named Lesson 25 Exercise File 1. Marvin is interested in whether blonds, brunets, and redheads differ with respect to their extrovertedness. He randomly samples 18 men from his local college campus: six blonds, six brunets, and six redheads. He then administers a measure of social extroversion to each individual. Conduct a one-way ANOVA to investigate the relationship between hair color and social extroversion. Conduct appropriate post hoc tests. On the output, identify the following: TASK THREE: PLACE OUTPUT HERE TASK FOUR: PLACE OUTPUT HERE TASK FIVE: ANSWER THESE QUESTIONS a. F ratio for the group effect b. Sums of squares for the hair color effect c. Mean for redheads d. P value for the hair color effect From Green & Salkind (2011). Copyright © 2012 Pearson Education. All Rights Reserved.

But do not strictly rely on your computer’s spell-checker and grammar-checker; failure to do so indicates a lack of effort on your part and you can expect your grade to suffer accordingly. Papers with numerous misspelled words and grammatical mistakes will be penalized. Read over your paper – in silence and then aloud – before handing it in and make corrections as necessary. Often it is advantageous to have a friend proofread your paper for obvious errors. Handwritten corrections are preferable to uncorrected mistakes. Use a standard 10 to 12 point (10 to 12 characters per inch) typeface. Smaller or compressed type and papers with small margins or single-spacing are hard to read. It is better to let your essay run over the recommended number of pages than to try to compress it into fewer pages. Likewise, large type, large margins, large indentations, triple-spacing, increased leading (space between lines), increased kerning (space between letters), and any other such attempts at “padding” to increase the length of a paper are unacceptable, wasteful of trees, and will not fool your professor. The paper must be neatly formatted, double-spaced with a one-inch margin on the top, bottom, and sides of each page. When submitting hard copy, be sure to use white paper and print out using dark ink. If it is hard to read your essay, it will also be hard to follow your argument.”>Comparing Means Worksheet

Comparing Means Worksheet
The following questions require that you access data from Using SPSS for Windows and Macintosh. This data is available under Resources in the Textbook Resources document. The team must work together to solve these questions.
1. Review the one sample t-test instructional video before completing this problem. The data set for this problem can be found through the Pearson Materials in the Textbook Resources link. The data for this question is in the data file named Lesson 22 Exercise File 1. John is interested in determining if a new teaching method, the involvement technique, is effective in teaching algebra to first graders. John randomly samples six first graders from all first graders within the Lawrence City School System and individually teaches them algebra with the new method. Next, the pupils complete an eight-item algebra test. Each item describes a problem and presents four possible answers to the problem. The scores on each item are 1 or 0, where 1 indicates a correct response and 0 indicates a wrong response. The IBM® SPSS® data file contains six cases, each with eight item scores for the algebra test.
Conduct a one-sample t-test on the total scores. On the output, identify the following:
