I must run data, schools-a.sav from www.Pyrczak.com/data and answer the following questions from Mertler & Vannatta pp 65 and 66 from chapter 3:

• you are interested in investigating if being above or below the median income (medloinc) impacts ACT mean 94 (act94) for schools. Complete the necessary steps to examine univariate and group data in order to respond to the questions below. Although deletions and/or trans-formations may be implemented from your examination, all steps will examine original variables.

I need to find the following:

Missing values for medloinc and act 94 severe split frequencies between groups what are the cutoff values for outliers in each group which outlying cases should be deleted for each group analyzing histograms, normal Q-Q plots, and test of normality, what is the conclusion regarding normality and if transformation is necessary (choose one to use) do the results from levene's test of equal variance, indicate homogeneity of variance? Does it indicate homogeneity of variance? if so, explain.

• examine variable scienc93, shows positively skewed distribution. transform variable using two most appropriate methods. which method produced a better alteration. Explain.

You are interested in studying predictions (math94me, loinc93, and read94 me) of the % graduating in 1994 (grad94).

examine univariate normality for math94me, loinc93, and read94m3. what's the conclusion about the distribution? what transformations should be conducted?

After making necessary transformations, examine multivariate outliers using Mahalanobis' distance. What cases should be deleted? after deleting the multivariate outliers, examine multivariate normality and linearity by creating a scatterplot matrix. examine the variables for homoscedasticity by creating residuals plot. what are the final conclusions about homoscedasticity?
