USE SPSS, SHOW WORK STEP BY STEP

A researcher wanted to know whether the level of frustration over high gas prices

differed for different types of vehicle owners. Following a sharp increase in the price

of gas, the researcher asked 30 people to indicate their level of frustration with prices

at the pump (frustration scores ranged from 1 to 10, with higher scores indicating

greater frustration). Ten people were surveyed who owned a motorcycle as their

primary means of transportation (coded a 1 in the data file), 10 were surveyed who

owned a hybrid vehicle (coded a 2 in the data file), and 10 were surveyed who owned a

nonhybrid vehicle (coded a 3 in the data file). The data are provided in the file Chapter

Open the file in SPSS and perform the

appropriate analyses to answer the questions below.

a. State the null and alternative hypotheses.

b. State a research question for the data.

c. Test for the assumption of equal variances. Do the data suggest unequal variances

between the groups? Test at = .05.

d. Is there a significant difference in the frustration levels of vehicle owners? Test at

= .05.

e. What is the effect size for the overall ANOVA? Would you characterize the effect

size as small, medium, or large?

f. If the overall ANOVA is significant, briefly summarize the results of Tukeys post

hoc procedure.

g. Write the results of the study using APA format as appropriate (be sure to include

the results of Tukeys test if the overall ANOVA is significant).
