An instructor wanted to know if his students are better at math or writing. He had students take both a math and then a writing test and he compared the results using SPSS. He found the following results: ( look at graphs ) a. What test was done?b. Report results in APA style.
INSTRUCTION: Perform an appropriate statistical test using the dataset (Sheet name: Cholesterol) if a researcher would like to determine if there is a significant difference in the "Cholesterol" level before ("Pre") and after ("Post") the treatment or therapy? Dataset for this can be retrieved on the given Excel. 1. What is the computed p-value for the given data on the "Cholesterol" level before ("Pre") and after ("Post") the treatment or therapy? Round it off to two decimal places. Then, answer (YES or NO) if there is a significant difference in the "Cholesterol" level before ("Pre") and after ("Post") the treatment or therapy? 2. What is the computed Mean of "Post" on the given data for Cholesterol? Round it off to two decimal places. 3. What is the computed Standard Deviation of "Pre" on the given data for Cholesterol? Round it off to two decimal places.

For each problem, you must state the hypotheses, calculate the test statistic, and explain your decision. The following table reports the relationship between class standing and political orientation for a random sample of 267 college students. a. The table is constructed assuming that class standing is the independent variable. Please add %s in the appropriate position (columns or rows) to describe the pattern of the relationship. b. Is there a statistically significant relationship between these variables?
Given the data: 1, 1, 3, 7, 7, 16, 21, 27, 30, 31. What score denotes the lower quartile, middle quartile, and upper quartile?
A student’s test grades are: 85, 75, 100, 90, and 90. On the two questions below, round to the nearest whole number when relevant. Show calculations and clearly report answers to each of the two questions below. a. What is the mean, or average, test grade for this student? b. What is the median test grade?
INSTRUCTION: Perform an appropriate statistical test using the dataset (Sheet name: Autism) if a researcher would like to determine if there is a significant difference between "Autistic," "Normal," and "Mentally Retarded"? The researcher took measurements of the serum concentration of an antigen in three groups of children (Autistic, Normal, and Mentally Retarded). Dataset for this can be retrieved on the given Excel. 1. What is the computed p-value for the given data on "Autism"? Round it off to two decimal places. Then, answer (YES or NO) if there is a significant difference in the serum concentration of antigen between "Autistic," "Normal," and "Mentally Retarded"? 2. What is the computed Mean of "Mentally Retarded" on the given data for Autism? Round it off to two decimal places. 3. What is the computed Standard Deviation of the "Autistic" group on the given data for Autism? Round it off to two decimal places.

Calculate the appropriate measure of association for this study. Round to the nearest hundredth. In a recent case-control study, investigators enrolled 300 adults with heart disease and 300 healthy adults. During interviews with the participants, the investigators determined participants' use of multivitamins in childhood, which was dichotomized into yes or no. The 2x2 table below shows the frequencies of heart disease case and control status by multivitamin use during childhood. Heart Disease Multivitamin Use Yes No Total Yes 125 175 300 No 135 165 300 Total 260 340 600 QUESTION 4 What is the correct interpretation of the measure of association you calculated in the previous question? (Please consider your calculated number in place of "X" in the answers.) The ODDS of heart disease among people who took multivitamins during childhood is X times the odds of heart disease among people who did not take multivitamins during childhood. The ODDS of multivitamin use during childhood among…
