1. Lab CPM1 LAB CPM. NATIONAL CONTEXT DIFFERENCES IN CORPORAL PUNISHMENT AND DATING PARTNER VIOLENCE “An example of “macro” level research. Also called “societal level” research if the cases studied are societies. Compare to previous lab which used “Individual level” data Most of the Lab Projects from here on will use “macro” or societal level data The Research Question The same question as for previous lab, but at the social system level and using “severe” assaults as the dependent variable: Do nations where corporal punishment is used by many parents have a higher probability of students severely assaulting a dating partner? Soc 695 Family Violence Research In World Perspective Murray A. Straus

2. Lab CPM2 HYPOTHESIS Write your hypothesis about the research question on the Lab Report Form. The hypothesis should use the word “nations” or more accurately “national contexts” to describe the cases The hypothesis could be different from the last lab because the cases are different and because the dependent variable is “severe” assaults, or it could be the same.

3. Lab CPM3 SAMPLE AND MEASURES SAMPLE: 32 nations covering every major world region INDEPENDENT VARIABLE = Corporal Punishment measured by Question 105. This is variable VS01 on the data cards. “When I was less then 12 years old, I was spanked or hit a lot by my mother or father.” 1 = Strongly disagree 2 = Disagree 3 = Agree 4 = Strongly Agree The variable is the percent of students in each national context who were spanked a lot, as indicated by the percent choosing answers 2, 3, or 4. DEPENDENT VARIABLE = Severe violence against a dating partner, as measured by the Conflict Tactics Scales score for Severe assaults on a dating partner in the past year. (questions are on the next slide)

5. Lab CPM5 THE DATA DATA FOR EACH NATION IS ON A DATA CARD * To fit the data for a nation on one card, the card for each nation has only about 80 of the 500+ variables * For purposes of this lab, each of you (or each team) will have the data card for one or two of the nations T HE VARIABLES ARE THE PERCENT OF STUDENTS IN EACH NATION OR THE AVERAGE FOR THE STUDENTS IN A NATION, FOR EXAMPLE: -- The percent of students who were spanked a lot before age 12 -- The percent of students who severely assaulted a dating partner THE CODE TELLS YOU THE VARIABLE THAT IS IN EACH BOX THE NAME OF THE NATION IS IN THE LOWER LEFT OF EACH CARD

6. Lab CPM6 TOP HALF OF DATA CARD This is the data on the percent who severe y assaulted a partner (9% for this nation) This is cell 1-2. Each cell of the data card has the score for one variable

7. Lab CPM7 BOTTOM HALF OF DATA CARD This is the data for the percent who were spanked or hit a lot before age 12 (52% for this nation. The nation where the university is located

13. Lab CPM13 TREND LINE TO SHOW THE RELATION BETWEEN THE PREVALENCE OF CORPORAL PUNISHMENT IN A COUNTRY AND THE PREVALENCE OF ASSAULTING A DATING PARTNER For each column of the tabulation form, circle the middle cell, even if it does not have a tally mark in it (this is the median) Take a card or ruler and connect the circles by a straight line. If there there is a tendency for the percent who were violent to a partner to increase from the left to the right side of the chart,.draw a line that shows the trend by sliding a ruler or other straight edge over the chart to get the best fit When this line is fitted mathematically it is called a “regression line” If this were done on a computer, the program would also give you a correlation or regression coefficient that indicates how good the fit between the dots and the line Sum the tally marks in each row & write the numbers in the TOTAL col. Computer generated regression line on next slide

14. Lab CPM14 Percent Spanked or Hit A Lot Before Age 12 (VS01) The correlation for this chart:.68, which is very high, but still deviations from the regression line. What would this chart look like if r =.99 or 1.00? (perfect correlation) What would it look like if r -.00 (no correlation) Significance test shows p <.001 What does that mean?

15. Lab CPM15 RESULTS & DISCUSSION SECTIONS OF THE LAB REPORT RESULTS SECTION Number & letter your answers. Use the term nation. You will need more space, so continue into the Discussion section. 1.How much corporal punishment was there? Answer this question from the Total row. Give the lowest. the highest rate and the median rate 2.How much severe violence to partners was there? This in the TOTAL column. 3A. What is the relation of corporal punishment to hitting a dating partner? 3B. How close or how strong a relationship do you think this is? 3C. Are the results statistically significant and what does that mean? 3D. Do the results support or not support your hypothesis? DISCUSSION SECTION What, in your opinion, do you think could produce result 3A? That is, what might be happening to create this relationship

16. Lab CPM16 RESULTS AND DISCUSSION SECTION OF THE LAB REPORT RESULTS SECTION (number your answers). You will need more space, so continue into the Discussion section of the form 1.How much corporal punishment was there? Answer this question by lowest and the highest rate and the typical rate 2.How much severe violence to partners was there? 3. What is the relation of corporal punishment to hitting a dating partner? 4. How close or how strong a relationship do you think this is? 5. Are the results statistically significant and what does that mean? 6. Do the results support or not support your hypothesis? DISCUSSION SECTION What processes do you think could produce result 3? That is, why do you think this relationship exists?

17. Lab CPM17 WHAT HAS BEEN LEARN ED FROM THIS LAB? RESULTS THE PREVALENCE OF CORPORAL PUNISHMENT WORLD-WIDE THE PREVALENCE OF VIOLENCE AGAINST DATING PARTNERS BY STUDENTS WORLD-WIDE WHETHER CORPORAL PUNISHMENT IS RELATED TO HOW VIOLENCE A COUNTRY IS METHODS HOW A SCATTER PLOT CAN BE USED TO TEST A HYPOTHESIS AN UNDERSTANDING OF THE FOLLOWING RESEARCH TOOLS: Regression line Correlation or regression coefficient Test of significance AN EXPERIENCE WITH EVALUATING DATA AND INTERPRETING RESULTS
