Psychological Statistics & 5 Calculating and Understanding Variability Homework 6 CH 4 Hand in both your answers and your work. Please report and label all your answers clearly and show your work as neatly as possible! Durracio et al. (2022) examined the effect of hours of sleep on eating behavior. They assigned one group of adolescents (14- to 17-year-olds) to Short Sleep (6.5 hours in bed) and one to Healthy Sleep (9.5 hours in bed) for 5 nights. For this example, we will look at the number of sugary drinks consumed per day (e.g., soda, Frappuccino, chocolate milk). Here are the data from both groups: Short Sleep X 7 5 6 3 3 3 2 1 0 0 Questions Healthy Sleep 3 3 2 2 2 1 1 1 0 0 the two levels. 1. Name the Independent Variable and 2. Name the Dependent Variable and its scale of measurement. 3. Calculate the measures of central tendency (Mean, Median, Mode) for each group. 4. For the Short Sleep group, compare to median what is the shape of the distribution? 5. For the Healthy Sleep group, compare to median - what is the shape of the distribution? 6. Calculate the measures of variability (range, IQR,) for each group. Show your work using the Raw Score formula for but ALSO calculate using the deviation formula to make sure your answer is the same for both. 7. Construct a boxplot for each group on the same graph (see Figure 5.3 in the text) 8. Write a sentence describing the number of sugary drinks each group drank. 9. Calculate the effect size (d) of the difference between the two groups, assuming = 2.60
