Using the same question from #3 A survey is done to find out the favorite movies of 500 children.  The children are categorized into male and female, and a sample of 50 children is chosen. Answer the following question: If the number of female children is 300, what is the sample size of each stratum?   a male sample: 40 and female sample: 10  b male sample; 25 and female sample: 25 c male sample: 30 and female sample: 20 d male sample: 20 and female sample: 30

What are the factors in a factorial design? A. The independent variables B. The experimental variables C. The organismic variables D. The dependent variables

Select the correct number of factors and levels for this study: A researcher would like to test if strategy type affects the time to complete an exam. The researcher assigns 24 student volunteers to one of the following 3 treatment groups: a group that crams for 12 hours before exam, a group that crams for 3 days before exam, and a group that studies for 1 week before the exam. a. 3 factors, 1 level b. 3 factors, 3 levels c. 1 factor, 3 levels d. 1 factor, 1 level

Psychologists at Disney World measured factors that affect the scariness of the soundtrack for their Haunted House ride. In particular, they were interested in the loudness of the screams (soft versus loud) and the length of the screams (short versus long). They used a 2 × 2 factorial design to test how these factors combined. They collected data from 10 different riders in each of the four conditions. Each rider rated the scariness of the ride on a nine-point scale. short screams long screams soft screams T=38, n = 10, SS = 13.6 T=64, n = 10, SS = 22.4 loud screams T=52, n=10, SS = 29.6 T=50, n=10, SS = 16.0 For these data: G = 204, N = 40, X2 = 1156. 1. Sketch a dataplot of the mean rating in each condition. 2. Calculate SS total, the total sum of squares 3. Calculate SSwithin, the within-treatments sum of squares. 4. Calculate SSbetween, the between-treatments sum of squares. 5. Calculate SSA the sum of squares for Factor A (length of scream). 6. Calculate SSB, the sum of squares…

Name each experimental design (a through e). Describe each factor - how many levels and the type of factor. Note: Gn denotes a group of subjects, and An, Bn, or Cn is a level of factor A, B, or C. [key words: ANOVA data, nested, factors, factorial design, between subject, within subject, etc.]
