psy355 SPSS Cumulative Assessment




Question;SPSS Cumulative Assessment Instructions;The following research questions can be answered using 1 of;the 5 tests you have learned so far: single-sample t-test, paired-samples t-test;independent-samples t-test, one-way;ANOVA, or two-way ANOVA. Use the information in the tables to construct your;SPSS data file, just as you have been doing in Part 2 of each homework;assignment. There is only 1 correct;choice of analysis for each question. The assessment is open-book/open-notes.;For each problem involving a test of significance, your;answer must include: A) the output and;an appropriate graph from SPSS, B) a;statistical statement (i.e., t(19) = 1.79, p =.049), and C) a sentence summarizing the results (i.e., ?There was a;significant difference between the two groups on the variable?? or ?There was;no significant difference??).;For ANOVA problems;Report statistical findings and make statements for all main effects and;interaction effects. Use the Fisher LSD test for any analyses requiring post;hoc tests.;Submit this assignment by 11:59 p.m. (ET) on Monday of;Module/Week 5.;1. An;entrepreneur claims that he has developed a program that can increase the IQ of;adolescent students. To test this claim, a psychologist administers the WISC;(an IQ score for children) to a group of students before and after completing;the training program. Analyze the data to test the entrepreneur?s claim.

The;staff at a local psychiatric facility wants to determine whether implementing a;No Smoking rule significantly decreases the length of stay of inpatients. In;order to test this claim, they compared the length of stay of patients admitted;before a No Smoking rule was implemented to another group of patients admitted after;the No Smoking rule was implemented. Evaluate the claim that the average length;of stay was significantly shorter for the group admitted after the facility implemented;the rule.

At the end of 3 months;each patient completes a standardized test of depression (higher scores;indicate higher level of depression). The patients? scores are shown below. Analyze;the data to determine how effective these 3 therapists are at treating;depression (assume that before the treatment, all 3 groups of patients had the;same average depression score).

In;light of all the weight loss misinformation and fad diets, a medical researcher;determines to evaluate several of them. She randomly assigns volunteers (identified;as clinically obese) to 1 of 4 diets. She is a firm believer in the benefits of;exercise, so she also assigns them to either the exercise or no exercise group.;After 3 months, she compares the pounds lost for each condition. Was there a;significant effect of the diets and exercise on weight loss?

Infants;exposed to cocaine in their mother?s womb are thought to be at high risk for;major birth defects. Thirteen infants born to mothers who are addicted to;cocaine are administered the Brazelton Neonatal Assessment 1 day after birth.;For these babies, their scores were as follows;Brazelton Scores;6.25;4.50;8.50;5.50;3.00;7.90;7.50;5.30;6.80;7.50;5.25;7.45;6.80;For the general population, babies normally score an 8.5. Is;this group of babies significantly lower than normal? (16 pts)
