Lesson 22, questions 1-4:

The data for Exercises 1 through 4 are in the data set named Lesson 22 Exercise File 1 on the Web at http://www.prenhall.com/greensalkind That data are from the following research problem.

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 SPSS data file contains six cases, each with eight item scores for the algebra test.

Exercise 1 :

Compute total scores for the algebra test from the item scores. A one-sample t test will be computed on the total scores.

Exercise 2 :

What is the test value for this problem?

Exercise 3 :

Conduct a one-sample t test on the total scores. On the output, identify the following:

1. Mean algebra score
2. t test value
3. p value

Exercise 4 :

Given the results of the children’s performance on the test, what should John conclude? Write a Results section based on your analysis.
