## One-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.

Note: If you run a one-way independent ANOVA, SPSS will not give you the SEM for each mean. To calculate them, you will need to use "Explore". You've done this before, but to jog your memory, go to Analyze > Descriptive Statistics > Explore.

On the ANOVA slide, you are asked to report the statistical results in correct APA format. This is illustrated below. Note: If you are having trouble inserting the symbols correctly into your pptx, you can copy and paste them from this document.

F (df,df) = actual value for F, p = the sig. value, ηp = the value for partial eta squared (note make sure the 2 is in superscript).

.

e.g. F(3,36) = 4.43, p = .043, ηp = .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. Note that the sample slide shows an LSD -t-test. I have asked you to use Tukey.

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: Conduct a one-way ANOVA to answer the question: Does political party affiliation have any effect on support for social actions to address climate change? Before conducting the ANOVA: for each participant, calculate their mean score on the "social action scale". Do NOT include the "validate" question. If the ANOVA is significant, be sure to run post hoc tests (Tukey or pairwise comparisons, depending on which type of ANOVA you ran). Make sure you choose the appropriate ANOVA!

American immigrants: Conduct a one-way ANOVA to answer the question: does political party affiliation have any effect on positive beliefs about immigrants? Before conducting the ANOVA: for each participant, calculate their mean score on the "positive beliefs scale". Do NOT include the "validate" question. If the ANOVA is significant, be sure to run post hoc tests (Tukey or pairwise comparisons, depending on which type of ANOVA you ran). Make sure you choose the appropriate ANOVA!

COVID vaccine and other mandates: Conduct a one-way ANOVA to answer the question: does political party affiliation have any effect on belief in COVID myths? Before conducting the ANOVA: for each participant, calculate their mean score on the "COVID myth scale". Do NOT include the "validate" question. If the ANOVA is significant, be sure to run post hoc tests (Tukey or pairwise comparisons, depending on which type of ANOVA you ran). Make sure you choose the appropriate ANOVA!

Gun violence: Conduct a one-way ANOVA to answer the question: does political party affiliation have any effect on support for firearm restrictions? Before conducting the ANOVA: for each participant, calculate their mean score on the "restriction support scale". Do NOT include the "validate" question. If the ANOVA is significant, be sure to run post hoc tests (Tukey or pairwise comparisons, depending on which type of ANOVA you ran). Make sure you choose the appropriate ANOVA!

Transgender discrimination: Conduct a one-way ANOVA to answer the question: does political party affiliation have any effect on familiarity with transpeople? Before conducting the ANOVA: for each participant, calculate their total score on the "familiarity scale". If the ANOVA is significant, be sure to run post hoc tests (Tukey or pairwise comparisons, depending on which type of ANOVA you ran). Make sure you choose the appropriate ANOVA!

Perceptions of discrimination at SUU-UT-USA: Conduct a one-way ANOVA to answer the question: does political party affiliation affect the belief that discrimination is a serious problem in the U.S.A.? Before conducting the ANOVA: for each participant, calculate their mean score on the discrimination in the United States scale. If the ANOVA is significant, be sure to run post hoc tests (Tukey or pairwise comparisons, depending on which type of ANOVA you ran). Make sure you choose the appropriate ANOVA!
