One section of the questionnaire, asking about focal children who were ages 1 to 4 years old, began with: "Sometimes children behave well and sometimes they don't. Have you had to spank your child when they behaved badly in the past week? About how many times have you had to spank your child in the past week? (number of times)" (M297)
a. What is the median number of times parents spanked their toddler in the past week, using the calculating formula presented in class?
b. In SPSS, find out the average number of times respondents spanked their 1-4-year-old boys and girls (F1SEX), respectively, in the past week, and paste it here. Then, calculate a t-test to determine whether there is a statistically significant difference in the average number of times parents spanked their 1-4-year-old child depending upon whether that child was a boy vs girl, and reach a conclusion.
Calculate and interpret a 99% confidence interval to estimate the difference (min to max) in the average number of times per week 1-4-year-old boys vs girls get spanked in the U.S.
d. In #2b, what is the independent and dependent variable, respectively?
e. Calculate and interpret a 95% confidence interval to estimate the true average number of times that mothers (M2DP01) in the U.S. spanked (M297) their 1-4-year-old boys (F1SEX) in the last week. (Note that you'll have to use the "Next" button in the "Compare Means" procedure to get the number you need)
Based on the coefficient of variation (you'll need to hand calculate), which group - women or men (mothers or fathers) - is more diverse when it comes to the number of times they spank their toddlers? Explain.
