PROJECT REQUIREMENTS

Project 3 requires that you use SPSS to conduct one-sample and independent samples t-tests. You will also report your statistical analyses using appropriate statistical language to demonstrate your statistical literacy. Use my headings and numbers for an organized report!

PART ONE: One Sample T-Test

The first test you will conduct is a one sample t-test (in SPSS). The one-sample t-test is very similar to the Z-tests we conduct in the first half of Chapter 8 (and the corresponding memo; the textbook authors use the t-distribution instead of the Z-distribution, which is discussed in the second half of Chapter 8 ).

For PART ONE, you will need to select a suitable variable for a one-sample t-test. Be sure your variable has a compatible level of measurement for this type of test. For this portion, your $\alpha$ is set at a $0.05$ level.

1. Report your variable name, its mean, median, mode, standard deviation, standard error, the minimum value, the maximum value, and the range (5 points).
2. Using the information obtained above, select a value to test for statistical significance. Report the following:
   - Write a two-tailed null and research hypothesis using symbols (5 points).
   - State the hypothesis using appropriate statistical language (5 points).
   - Explain why you chose the test value for the statistic and what it means, in words. (5 points).
3. Report and label the following (5 points):
   - mean difference
   - the degrees of freedom
   - the obtained t-statistic
   - the t-critical
   - the P value
4. Using appropriate statistical language, make a decision regarding your hypotheses (10 points).
5. Using the information gathered, explain what your results and decision mean in words (15 points).
   PART TWO: Independent Samples T-Test
   The second test you will conduct is called an independent samples t-test (in SPSS). These tests are covered in the second half of Chapter 8 .
   For PART TWO, you will need to select a suitable variable upon which to conduct independent samples t-test. This variable MUST be DIFFERENT from the one you selected for the first part of the assignment.
6. Report the variable name, mean, median, mode, standard deviation, standard error, the minimum value, the maximum value, and the range of the new variable (5 points).
7. Select "sex" as your grouping variable. Report the mean, standard deviation, and standard error of the mean of your chosen variable for both the 'male' and 'female' groups (5 points).
8. Using symbols, write two-tailed null and research hypotheses ( 5 points). In words, state the hypotheses using appropriate statistical language ( 5 points).
9. Assuming equal variances, report the following information ( 5 points):
   - the mean difference (1 point)
   - standard error of the difference (1 point)
   - the obtained t-statistic (1 point)
   - the degrees of freedom (1 point)
   - the t-critical (1 point)
   - the P-value (1 point)
10. Using appropriate statistical language, make a decision regarding your hypotheses (10 points).
11. Using the information obtained, explain what your results mean in words (15 points).
