By Day 3
Use SPSS to answer the research question you constructed and post your response to the following:
Review the Learning Resources and the media programs related to t tests. Using the SPSS software,...
Using the SPSS software, open the Afrobarometer dataset or the High School Longitudinal Study dataset (whichever you choose) found in the Learning Resources for this week. Based on the dataset you chose, construct a research question that can be answered with a multiple regression analysis. Create a research question with metric variables and one variable that requires dummy coding. Estimate the model and report results. Note: You are expected to perform regression diagnostics and report that as well.
Create a research question using the General Social Survey that can be answered by multiple regression. What is your research question? What is the null hypothesis for your question? What research design would align with this question? What dependent variable was used and how is it measured? What independent variable is used and how is it measured? What other variables were added to the multiple regression models as controls? What is the justification for adding the variables? If you found...
Instructions For this Assignment, review this week’s Learning Resources, including the 5-step approach to hypothesis testing document. Read the research scenario, below, and then answer the questions related to the steps that must be followed to make the appropriate decision as to reject, or fail to reject, the null hypothesis. Research Scenario Hematocrit levels (g/dL) from healthy term infants form a normal distribution with m = 61 and s = 7. Several studies have shown that the risk of anemia...
Research question #3. Does the quality of therapist-client relationship affect the change of the scores from pre-test to post-test among juveniles? (13 points) SPSS Dataset SPSS Data for HW (500 cases).sav (available in Canvas) change: Change of the scores from pretest to posttest (measured by points) qual: Quality of therapist-client relationship (measured by points) Variable Names in the dataset 1. What are the dependent variable (DV) and independent variable (IV)? (1 point) 2. State the research hypothesis (non-directional) and the...
Part II: SPSS Application These questions require the use of SPSS. Remember you must submit all of your work within this word document. You will need to take a screen shot of your data view if necessary, or copy and paste your output into the spaces below. Remember to report the exact p value provided by SPSS output – simply reporting p<.05 or p>.05 is not acceptable (unless SPSS output states p=.000 – in that case you can report p<.001)....
Comparing two means: When drink drove a student to statistics (Rubric included) Instructions For this assignment, you review this week’s Learning Resources and then perform a two-sample independent t test and an ANOVA related to the dataset that was utilized in the week 2 SPSS application assignment. Import the data into SPSS; or, if you correctly saved the data file in Week 2, you may open and use that saved file to complete this assignment. Type your answers to all...

Open the "Lab Dataset" (HSCI390.sav) you have been using for lab assignments in SPSS. Your analysis will focus on the variables "Gender" (Gender) and "Blood Alcohol Content at last drinking episode" (BAC). Researchers are interested in examining if the mean Blood Alcohol Content at last drinking episode differs between men and women. To examine their research question of interest, they will use data from the sample of CSUN students contained in the HSCI390.sav dataset. Using SPSS for the analysis, you...
Use the GSS dataset to answer the questions below. All analysis must be completed using your own GSS data set. Failure to use your own GSS data set will result in a zero for the question. As above, you will need to read and interpret the question to determine which statistical test is appropriate, as well as whether it is a one-tailed or two-tailed test. Similar to the questions above, you must: 1. State the null and research hypotheses 2....
Psy 248: STATISTICS- MARIA MIRANDA Computer Lab Assignment II, SP 2019 Comparing means using t-tests This assignment will give you practice choosing the appropriate test statistic to use for different research designs that all involve comparing using t-tests. You will need to enter the data, use SPSS to test hypothesis, and write a conclusion for each problem stating weather or not the samples differed significantly. To run all 3 tests, use: ANALYZE, COMPARE MEANS, and then select the type of...
