IMPACT OF MODULEA sample of 10 students were given a diagnostic test before studying a particularmodule and then again after completing the module. We want to find out if, ingeneral, teaching leads to improvements in students' knowledge/skills. We canuse the results from our sample of students to draw conclusions about the impactof this module in general. Assume in this example, that the data may not benormally distributed and that it is necessary to use non-parametric statistics.STUDENTPRE-MODULEPOST-MODULESCORESCORE1182222125316174222419166.242971720821239.2319101820B.

IMPORTANT NOTE: As per the recommendations in the Mid-Summer Evaluations, the vast majority of you stated that the Unit 1 Homework Set needed more practice on the Empirical Rule to be more helpful for the Unit 1 Test. Therefore, I have designed a problem (this one) to replace one of the oversaturated scales of measurements problems. Additionally, this counts as up to two points of extra credit onto your overall Homework Score. This is not mandatory to complete. Finally, if you are willing to share your thoughts on whether or not the inclusion of this problem would improve the set, then please do so by copying-and-pasting the following link into your address bar: https://www.strawpoll.me/46102512 Suppose that the Unit 3 Test has an average of a 69 with a standard deviation of 10 points. Additionally, the test scores are known to follow a Gaussian distribution Which of the Empirical Rule or Chebyshevs Theorem will be used here and why? OA. We will use Chebyshevs Theorem because the…
QUESTION 18 A researcher notes that there seems to be a difference in the prevalence of high blood pressure among college-educated individuals who consume low amounts of processed foods and the prevalence of individuals who only have a high school education and consume high amounts of processed foods. Use the appropriate hypothesis to test for the independence of the two independent variables presented here at the 5% significance level to ensure confounding has not influenced the study’s results. Then, interpret your response. Diet Low in Processed Foods Normal BP High BP Total College Education 124 55 179 High School Education 69 152 221 Total 193 207 400 Diet High in Processed Foods Normal BP High BP Total College Education 64 85 149 High School Education 98 153 251 Total 162 238 400 The chi square value of 37.724 is higher than the chi square value of 3.84; therefore, we do not reject H0 at the 5% level and reject H1, which states that level…

Thirty hectares were planted with the rice varieties exposed to fairly uniform growing conditions. The results are obtained as follows: Variety A Variety B Average Yield 80 sacks/hectare 35 sacks/hectare Sample variance 5.9 12.1 At 0.05 significance level, can we conclude that variety A is the better type?

7. Effect size - Cohen's d and r squared An industrial/organizational psychologist has been consulting with a company that runs weekend job-seeking workshops for the unemployed. She collected data on several issues related to these workshops and, after conducting statistical tests, obtained statistically significant findings. She needs to find a way to evaluate effect size so that she can make recommendations to the company. One of the psychologist’s findings is that 18 months after the workshop, a sample of 36 job seekers who received training on resume writing scored an average of 7.3 as measured on a 9-point job-search motivation scale, with a standard deviation of 1.5. The typical job seeker scores 6.1 points. The psychologist finds that the estimated Cohen’s d is , the t statistic is 4.80, and r² is . Using Cohen’s d and Cohen’s guidelines for interpreting the effect size with the estimated Cohen’s d, there is a treatment effect. Using r² and the extension…
The hypothesis should revolve around one of the variables collected for all subjects. Your results section should describe the general course of one subject’s response from your individual analysis and then evaluate your hypothesis for a specific collective variable. Please explain this in plain english. I dont understand the instructions. Here is a reference of the subjects.
