1.First, based upon the dataset from the nationally conducted High School and Beyond study (hsb.sav), generate a correlation matrix for the following variables: mathach(math achievement test), mosaic(mosaic pattern test), visual(visualization test), competence(total of competence in math survey items), motivation (total of motivation in math survey items), and satm (SAT math score).
You have to specify what type of correlation test should be used and justify your choice. Interpret the output and write up the data results.
2.Using the same dataset, run a SPERAMAN'S RHO correlation test using TWO variables of YOUR CHOICE. Discuss why such two variables are used and specify the research question you'd like to address in this test. Report the result.
Section two:
1.Carefully examine all variables in the data set. Pick TWO appropriate variables to run a Simple Regression analysis. Propose a meaningful RQ, and write null hypothesis and alternative hypothesis.
2.Discuss TWO assumptions in this assignment: a) are those variables interval/ratio? b) create scatterplot to plot the DV against IV and visually inspect to check for linearity.
3.Run a simple regression analysis in SPSS and write results.
