Question

Please note that for all problems in this course, the standard cut-off (alpha) for a test of significance will be .05, and you always report the exact power unless SPSS output states p=.000 (you’d report p<.001). Also, remember when hand-calculating, always use TWO decimal places so that deductions in grading won’t be due to rounding differences.

Problem Set 1: A child trauma counselor knows that for her region, 15% of children are in extreme poverty, 50% are below poverty, and 35% of the children are above the poverty level. She wants to know if her services reaches a similar demographic to what is known in the region. Services provided at each demographic level for her 36 clients are provided in the table below. Hint: Review Week 4.    Extreme poverty Below poverty Above poverty 8 15 13

1. Paste appropriate SPSS output. (2 pts)

2. Paste appropriate SPSS graph. (2 pts)

3. Write an APA-style Results section based on your analysis. All homework “Results sections” should follow the examples provided in the presentations and textbooks. They should include the statistical statement within a complete sentence that mentions the type of test conducted, whether the test was significant, and if relevant, effect size and/or post hoc analyses. Don’t forget to include a decision about the null hypothesis. (2 pts)

Answer 1

The Chisquare goodness of fit test reports the test statistic value 3.098 with 2 DF and associated p value .212, which indicates that the test was not significant and hence we conclude that counselors  services reaches a similar demographic to what is known in the region.
