Textbook Question

Chapter 11.4, Problem 9BSC

Head Injury Crash Test Data Exercises 1–4 use chest deceleration data for three different size categories (small, midsize, large). The data are from a standard crash test and they are listed in Data Set 13 in Appendix B. If we use the head injury measurements (in HIC, which is a standard head injury criterion) with the same three size categories, we get the SPSS results shown here. Using a 0.05 significance level, test the claim that the three size categories have the same mean head injury measurement. Does the size of a car appear to affect head injuries?

Definition Definition Measure of central tendency that is the average of a given data set. The mean value is evaluated as the quotient of the sum of all observations by the sample size. The mean, in contrast to a median, is affected by extreme values. Very large or very small values can distract the mean from the center of the data. Arithmetic mean: The most common type of mean is the arithmetic mean. It is evaluated using the formula: μ = 1 N ∑ i = 1 N x i Other types of means are the geometric mean, logarithmic mean, and harmonic mean. Geometric mean: The nth root of the product of n observations from a data set is defined as the geometric mean of the set: G = x 1 x 2 ... x n n Logarithmic mean: The difference of the natural logarithms of the two numbers, divided by the difference between the numbers is the logarithmic mean of the two numbers. The logarithmic mean is used particularly in heat transfer and mass transfer. ln x 2 − ln x 1 x 2 − x 1 Harmonic mean: The inverse of the arithmetic mean of the inverses of all the numbers in a data set is the harmonic mean of the data. 1 1 x 1 + 1 x 2 + ...

Information regarding the ACT scores of samples of students in three different majors is given below. Major Management Finance Accounting Sample size 12 10 18 Average 24 26 27 Sample variance 18 6 10 a. Compute the overall sample mean x b. Set up the ANOVA table for this problem including the test statistic. Include all qork c. Using a = .05, determine the range of critical values for F. d. Using the critical value approach, test to determine whether there is a significant difference in the means of the three populations within the context of this scenario.

This data set contains the achievement test (English as a Second Language) results and some background data collected during experimental trial of a new ESL program. The study was one year in duration. Students were allocated to the experimental ESL program class and a regular program control class on a random basis. Vocabulary and grammar tests were administered to the students in both groups at the beginning and the end of the school year. Variables The dataset includes 24 cases and 7 variables: ▪ Student ID ▪ Group (1 - experimental, 2 - control, 9 - missing) ▪ Gender (1 - male, 2 - female, 9 - missing) ▪ Pre-test vocabulary scores (scores range from 0 - 25, 99 - missing) ▪ Pre-test grammar scores (scores range from 0 - 25, 99 - missing) ▪ Post-test vocabulary scores (scores range from 0 - 25, 99 - missing) ▪ Post-test grammar scores (scores range from 0 - 25, 99 - missing) Provide a codebook with the following four columns: (1) Variable name; (2) Variable label; (3) Value &…
