PSYC 355;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 twoway 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 entrepreneurs 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 mothers 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)
