What is a unique advantage of the Latin Square design? It reduces the carryover effect while maximizing the strength of the IV manipulation. The Latin Square design uses multiple langauges. It counterbalances while reducing the number of groups/people needed to control for order effects. It is useful in an independent groups designs when matching participants on the dependent variable.

- Explain how a within-subjects design avoids the problems created by individual differences and how a between-subjects design avoids the problems created by order effects.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…Please do not give solution in image format thanku
- Education Influences attitude and festyle. Differences in education are a big factor in the "generation gap." Is the younger generation really better educated? Large surveys of people age 65 and older were taken in n, = 37 U.S. cities. The sample mean for these cities showed that x, 25.2% of the older adults had attended college. Large surveys of young adults (age 25 - 34) were taken in a,- 32 U.S. attes. The sample mean for these aties showed that x, = 19.6% of the young adults had attended college. From previous studies, t is known that o, - 6.H% and o, 5.6%. Does this Information Indicate that the population mean percentage of young adults who attended college Is higher? Use a = D.05.

During the application process the potential members are asked which recreational activity they do the most. Their choices are fishing, skiing, boarding, swimming, or tubing. The lake manager chooses clients according to their interests to maximize the use of all areas of the lake. Every month, the lake rangers randomly sample the boats on the lake and categorize them according to the activity they are doing. The lake manager performs a chi-square goodness-of-fit test using the following null hypothesis to see whether their samples differ significantly from what the original applications claim. Ho Pfish =0.26, p,ki = 0.21, proard 0.21, Phoard 0.30, Psuim 0.12, Prube 0.11 In order to meet the conditions for independence and large counts for a chi-square goodness-of-fit test, which of the following represents all possible sizes of the monthly samples?

How do you identify which variable in a study is the factor? How do you identify the levels of a factor? How do you identify the dependent variable?Help.Diana tested the effect of number of items on short-term memory in dolphins. She randomly presented visual arrays with 1, 2, 3, 5, 8, 13, 21 items for five minutes. She asked 3 dolphins to remember the items. She then presented a new array with old and new items. The dolphins responded by touching the items with their tails. She hypothesized that Dolphins could remember 3 items accurately, but not more than that. How many pairwise comparisons should she do according to the recommended guideline?Recommended textbooks for youMATLAB: An Introduction with ApplicationsStatisticsISBN:9781119256830Author:Amos GilatPublisher:John Wiley & Sons IncProbability and Statistics for Engineering and th…StatisticsISBN:9781305251809Author:Jay L.
