3. A researcher is investigating the effect of background noise on classroom performance for children aged 10 to12. One class of N = 15 students who listens to calming music each day while working on arithmetic problemsis chosen as the experimental group. Another class of N = 16 students serves as a control group with no music.Accuracy scores are measured for each child, and the average for students in the music condition is X = 86.4with SS = 1550. For the no-music condition, the average is X= 78.8 with SS = 1235. (d) Compute and interpret a Bayes factor for the model (either H₁ or H₁) with the best predictive adequacy.(e) Compute and interpret the posterior model probability for the winning model chosen in part (d).

The given problem involves investigating the effect of background noise on classroom performance for…

OSE 2 Researchers conducted a study to estimate the relationship between a subject's brain activity while watching a television commercial and subject's subsequent ability to recall the contents of commercials. People think that long commercial recall is remembered by the people compared with the short one. In order to understand the difference researcher made 10 long commercial and a short one for each products and commercials are watched by the same person. Then subjects are asked what they remembered from the commercial and giving the correct answers are codded by the following table. 1 2345678910 Long Commercial Recall 108668 9786 Short Commercial Recall 4 23444462 2 Ce Test the claim that long commercials recall is more than short one (The duration of the commercial make a difference to recall).

A researcher found that the two groups (n=25 in each group) they tested were significantly different from each other with a t-value of 2.91, which has a corresponding p-value of p=.06. For this study, report the statistics in APA format.
A researcher would like to examine how the chemical tryptophan, contained in foods such as turkey, can affect mental alertness. A sample of n = 9 college students is obtained and each student’s performance on a familiar video game is measured before and after eating a traditional Thanksgiving dinner including roast turkey. The average score dropped by M = 14 points after the meal with SS = 1152 for the difference scores. A. Is there is significant difference in performance before eating versus after eating? Use a two-tailed test with α = .05. SMD = ___________________________ tcritical = ________________________ tcalculated = ________________________ Decision = _______________________ B. Compute r2 to measure the size of the effect. r2 = _____________________________ C. Write a sentence demonstrating how the outcome of the test and the measure of effect size would…

Hi I know that you can’t answer all questions. Can you just answer question 21 please.
The results obtained above were primarily due to the mean for the third treatment being noticeably different from the other two sample means. For the following data, the scores are the same as above except that the difference between treatments was reduced by moving the third treatment closer to the other two samples. In particular, 3 points have been subtracted from each score in the third sample. Before you begin the calculation, predict how the changes in the data should influence the outcome of the analysis. That is, how will the F-ratio for these data compare with the F-ratio from above? Treatment A Treatment B Treatment C 4 6. 7 3 9. 3. 4 3. F-ratio = p-value = Conclusion: O These data do not provide evidence of a difference between the treatments There is a significant difference between treatments Submit Question M hp
On average, a sample of n = 36 scores will provide a better estimate of the population mean than a sample of n = 49 scores from the same population.
A researcher gives a depression scale to 300 people now, 6 weeks later, and 6 months later. She finds that the depression scale means are relatively the same over those three time periods. Does this mean that the depression scale is valid, and/or reliable? Explain.

Q1. A psychologist conducted a study on the relationship between introversion and shyness. The values are results for scales of introversion and shyness. High positive scores on each scale indicate high introversion or shyness; and high negative scores indicate low introversion or shyness. Data collected from 10 people as follows: Introversion 4 -7 -1 0 6 7 -4 -9 -5 8 Shyness 11 -7 -1 -3 0 7 -1 -8 -1 5 a) Compute the correlation coefficient relating introversion and shyness scores. b) Find the regression equation which predicts introversion from shyness. c) What introversion score would you predict from a shyness score of 7?
In a data set with 25 scores, if the value 16 occurs 12 times, what is its relative frequency?
