In the first study, the difference between Group A and Group B is two points. However, the \u03c3M1-M2<\/sub>\u00a0is large, and the difference is not significant. In the second study, the difference between Group A and Group B is also two points. However, the \u03c3M1-M2<\/sub>\u00a0is small, and the difference is significant. What might be the reason for the difference in the \u03c3M1-M2<\/sub>\u00a0across the two studies?<\/p>\n A researcher is examining the effects of a new anxiety drug. The \u03c3M<\/sub>\u00a0for the experimental group (group receiving the antianxiety drug) is 1.4, while the \u03c3M<\/sub>\u00a0for the control group is 1.22. Calculate the \u03c3M1 \u2013 M2<\/sub>\u00a0.<\/p>\n Complete the following steps:<\/p>\n A VP for a large clothing retailer is convinced that handing out coupons to customers in the store will leader to higher sales. To test this, she has her sales associates randomly select customers to either receive or not receive a $10-off, today-only coupon. As each customer leaves the store, the amount of his or her purchase is recorded. The recorded data are in SPSS file\u00a0assessment4b.sav\u00a0linked in the Resources under the Required Resources heading.<\/p>\n Complete the following:<\/p>\n Identify whether independent samples were used, repeated measures were used, or matched samples were used in the following scenarios:<\/p>\n Complete the following steps:<\/p>\n A study was conducted on information retention in 40 students (20 pairs) after students conducted online research or watched a movie on a given topic. Students were matched on gender and age. Data provided in the SPSS file below represent quiz scores after students completed their studying.<\/p>\n Complete the following:<\/p>\n Refer back to your SPSS output from Assessment 4 Question 3. Based on that output, what is the 95 percent confidence interval of the difference?<\/p>\n Assume the within-group deviation is 108.45 and the between-group deviation is 48.68. Calculate the total deviation.<\/p>\n Assume MSbet<\/sub>\u00a0= 80 and MSwith<\/sub>\u00a0= 20. What is F?<\/p>\n Answer questions a\u2013d using the following ANOVA summary table:<\/p>\n Complete the following steps:<\/p>\n A teacher believes that kindergartners who attend school for a full day are more proficient readers than those children who attend for a half day or those who are homeschooled. At the end of the school year, she gives a reading test to 20 full-day kindergartners, 20 half-day kindergartners, and 20 home-schooled kindergartners. Data provided in the SPSS file\u00a0assessment4f.sav\u00a0below represent reading scores for each group:<\/p>\n Complete the following steps:<\/p>\n Complete the following steps:<\/p>\n Complete the following steps:<\/p>\n Assessment Instructions Answer the questions below, following the Submission Requirements as specified at the end of the assessment.
