1 way ANOVA

Submit after you review your feedback from SPSS assignment 7.

Each team will run a one-way ANOVA - independent or repeated as appropriate - on the variables I tell them to. Scroll to the end of this page to find out what your team's analysis will be.

 

Each team will create and submit 2-3 pptx slides: 1-2 slides for their ANOVA, post hoc test information (if needed), and EXCEL graph. The last slide will include the relevant SPSS output with the numbers used hi-lighted. Make sure you include the SPSS output showing the means and SEMs used in your graph, and not just the Levene's test, ANOVA, and post hoc test results.

 

On the ANOVA slide, you are asked to report the statistical results in correct APA format. This is illustrated below:

(df,df) = actual value for F, = the sig. value, ηp2 = the value for partial eta squared (note that the 2 should be raised in superscript).

.

e.g.  F(3,36) = 4.43, p = .043, ηp2 = .125    You can choose between reporting the actual sig. value, p >.05 or p<.05 as appropriate and whichever will look more impressive. Remember our discussion in class about this?

Please see this sample pptx for what goes on the ANOVA slide. The partial eta squared statistic is missing. Make sure you include yours.

 

The video library has a clip on how to add SEMs (also called y-error bars) to graphs.

 

Please let me know if you have any questions!

Climate change: First, go the the question that asked about the extent to which participants agree with examples of climate change. There are three questions in this grouping. The first is "Global climate change is largely the result of human activity". Calculate the mean score for all three questions for each particpant. This new variable will be the DV. Now conduct a one-way ANOVA to answer the question:  Does political party affiliation have any effect on the extent to which people believe that recent events on earth are the result of global warming? If the ANOVA is significant, be sure to run post hoc tests.

American immigrants:  First, go the the question that asked about the extent to which participants agree with the good (positive) impact immigrants have had on the U.S. There are three questions in this grouping. The first is "Immigration to the U.S. has, overall, benefited the United States". Calculate the mean score for all three questions for each particpant. This new variable will be the DV. Now conduct a one-way ANOVA to answer the question:  Does political party affiliation have any effect on the extent to which people believe immigrants have positively impacted the United States? If the ANOVA is significant, be sure to run post hoc tests.

COVID vaccine and other mandates: First, go the the question that asked about vaccine myths. There are nine questions in this grouping. The first is "COVID-19 vaccines are experimental and untested". HOWEVER, ignore the two questions that state that COVID vaccines are safe and effective. This will leave you with 7 questions. Calculate the mean score for all 7 questions for each particpant. This new variable will be the DV.  Now conduct a one-way ANOVA to answer the question:  Does political party affiliation have any effect on the extent to which people believe in vaccine myths? If the ANOVA is significant, be sure to run post hoc tests.

Gun violence: First, go the the question that asked about the extent to which participants agree with the statements regarding gun restictions. There are four questions in this grouping. The first is "Except for hunting rifles, personal gun ownership should be completely banned". Calculate the mean score for all four questions for each particpant. This new variable will be the DV. Now conduct a one-way ANOVA to answer the question:  Does political party affiliation have any effect on the extent to which people support gun restrictions? If the ANOVA is significant, be sure to run post hoc tests.

 

Transgender discrimination: First, go to the two questions; "Transmen are discriminated against in the U.S." and "Transwomen are discriminated against in the U.S." Calculate the mean score for these two questions for each particpant. This new variable will be the DV. Now conduct a one-way ANOVA to answer the question:  Does religious affiliation have any effect on the extent to which people believe transmen and transwomen are disciminated against in the U.S.? If the ANOVA is significant, be sure to run post hoc tests.

 

Perceptions of discrimination at SUU-UT-USA:  Are perceptions of 7 forms of discrimination different depending on the reference location (SUU, UT, USA)?  To find out, for each reference location, you will need to look at the 7 questions about discrimation. The first one is "Sex discrimination is a serious problem".  Then, for each reference location you will need to calculate the mean discrimination score for each participant. This will create three new variables: discimination-SUU, discrimination-UT, and discrimination-USA. Conduct an ANOVA to compare the means for these three "conditions". If the ANOVA is significant, be sure to run post hoc tests.
