SPSS Interpretation ( 26 points) For your Prelabs and Labs in Unit 3, you evaluated differences among children attending Head Start programs as rated by their teachers. Some of the variables were measures of positive characteristics (Initiative, Attachment, Self-Control, and Play Interaction). Other variables were measures of behavioral challenges (Play Disruption, Play Disconnection, and Behavioral. Concerns). Some of the children had been identified as "at risk" and participated in a playgroup intervention at their preschool from fall to spring, You compared average scores on some of the these variables between the "at risk" children and their "not at risk" peers. You also looked at changes in these variables from fall to spring - among all children, and also within the "at risk" and "not at risk" groups separately. Finally, in Lab 5, you used Oneway ANOVA to test the hypothesis that children with high levels of protective factors (combined score of Initiative, Attachment, and Self-Control divided into four levels) were more likely to have lower levels of behavioral challenges. For the questions in this section, you'll be considering parent ratings of these variables, obtained about the same time as the teacher ratings. Consider the research hypotheses below, using the parent ratings provided: 1. Fall Play Interaction of "at risk" children is lower, on average, than that of "not at risk" children. 2. Play Interaction of "at risk" children is lower, on average, in the fall than in the spring. 3. Play Interaction of "not at risk" children is lower, on average, in the fall than in the spring. In addition, children have been categorized into three age groups: a. Age \( 2.8 \) years to \( 3.59 \) years b. Age \( 3.6 \) years to \( 4.2 \) years c. Age \( 4.3 \) years to \( 4.7 \) years 4. Play Interaction is highest in the oldest age group. SPSS Analyses and related questions for these research hypotheses are on the next page. Use \( \alpha= \) \( .05 \) for all hypothesis tests. Read the questions on the following pages carefully. Provide whatever is requested. 1 point each except where otherwise noted. 4. Is HOV justified? Clearly identify the ourpit that you used to deternine your answer. 5. Is the difference between groups signifieant? Clearly identify the output that you used to determine your answer. 6. Describe the difference between the two means and your interpretation of the SPSS output, followed by the publication format, including the Confidence Interval. (4 points) Rescarch Hypothesis 2.: Play Interaction of "at risk" children is lower, on average, in the fall than in the spring. Rescarch Hypothesis 3.4 Play Interaction of "not at risk" children is lower, on average, in the fall than in the spring. 1. State the null bypothesis in words: 2. Will you do a one-tailed or two-tailed test? 3. Looking at these descriptive statisties, is the children's mean Play Interaction of the "at risk" group lower in the fall than in the spring? Researeh Iypothesis 4.t Phy Interactios is highest in the oldest age group. 1. Looking at these descriptive statistics, is children's mean Play Interaction of the oldest group higher than the younger groups in the fall? 2. Looking at these descriptive statistics, is children's mean Play Internction of the oldest group higher than the older groups in the apring? 3. Are any of these differences significant in the fall? 4. Are any of these difierences significant in the spring? 5. Write up the results in a. sentence or two, including publication format for both.
