A school wants to evaluate the effectiveness of three different teaching methods in improving students' test scores.The three methods are traditional, project-based learning, and cooperative learning. Each method was taught to 20 randomly selected students from three different classes. the average scores of the students for each method were as follows: Method Mean Standard Deviation Traditional 75 8 Project-Based 82 6 Cooperative 78 7 how to determine whether there is any significant difference in the scores among the three teaching methods?

Mandrake Falls High School is providing a weekend course in laboratory techniques to its laboratory students. Of the 200 students enrolled in lab classes at Mandrake, 78 have taken the weekend course. Mandrake is evaluating the course's effectiveness by having its lab instructors record harmful lab "incidents": accidents, misuse of lab equipment, etc. The contingency table below gives a summary of the data that have been gathered so far for Mandrake's 200 lab students. Each student is classified according to two variables: status regarding lab techniques course ("Took the course" or "Didn't take the course") and laboratory performance ("Involved in no incident", "Involved in exactly one incident", or "Involved in 2+ incidents"). In the cells of the table are the respective observed frequencies. Note that three of the cells also have blanks. Fill in these blanks with the frequencies expected if the two variables, status regarding lab techniques course and laboratory performance, are…
There are three available methods to provide dietary information to students: (1) through an online website; (2) from a nurse; (3) from a pre-recorded video. Thirty-three (33) students were randomly assigned to evaluate which of the three methods of delivering dietary information is most superior. The respondents are asked to rank each method based on difficulty, usefulness and importance, to determine if there is a difference in the modes of presentation What are the dependent and independent variables? are there covariates
A psychologist studied the alcohol consumption patterns of people in two age groups. One group consisted of people aged 21 to 35, and the other consisted of people aged 36 to 50. The psychologist interviewed random and independent samples from each group. She assigned a score from 0 to 100 to each individual (a score of 0 meant no alcohol consumption) according to factors such as the frequency and the amount of alcohol consumed. The results from the study are summarized below.
"Snoqualmie" is a name shared by a waterfall and a tribe of Native Americans. In a study of the cultural importance of the waterfall, two groups of the Snoqualmie tribe were randomly surveyed. One group consisted of Snoqualmie members living less than 25 miles from the waterfall. Another group consisted of Snoqualmie members living more than 25 miles from the waterfall. The researchers asked each member to rate the cultural importance of the waterfall as low, medium, or high. Data from the study are presented in the following table. Members Living More Than 25 Miles from the Waterfall Members Living Less Than 25 Miles from the Waterfall Total Low 25 17 42 Medium 8 21 29 High 12 17 Total 38 50 88 If the distributions of ratings are the same for those Snoqualmie members living less than 25 miles from the waterfall and those living more than 25 miles from the waterfall, which of the following is equal to the expected count of members living less than 25 miles from the waterfall who rated…

Dr. Caldwell was also interested in learning whether the anxiety of child victims is related to whether they testify in court. She conducted another research study in which she compared the anxiety levels of 10 children who testified to the anxiety levels of 10 children who did NOT testify. She measured the children’s anxiety using the same test described earlier - the Beck Anxiety Inventory for Children (BAI-C). The scores of the 20 children are as follows: TestifiedDid NOT Testify 5554 5762 5072 6269 6673 4858 7175 6063 7070 5266 11. Conduct an independent measures t-test to determine whether Dr. Caldwell can conclude that there is a significant difference between child victims who testify and those who don’t with respect to anxiety. Show all 4 steps of hypothesis testing, and calculate a measure of effect size. Use a 2-tailed test with α = .05 Step 1: Step 2: Step 3: show calculations and values for: M and SS for each group, the pooled…
PSE&G has a reputation for fixing any electric system problems quickly. Over the past decade various severe storms caused a problem with electrical service. In a sample of seven severe storms, it took the following number of days to restore service: 13, 12, 8, 3, 8, 2, 28. Management at PSE&G feels the 28 days were recorded in error (should be either 2 or 8) and should not be used in any analysis. How do you respond to management? (must prove statistically). Some information you may or may not need include: mean = 10.6, median = 8; standard deviation = 8.1, variance = 65.5 and range = 26.
