Complete the following end of chapter exercises for Chapter 3. Submit your response in an MS Word document or Pdf after inserting the results from SPSS Output into your document. This exercise utilizes the data set schools-a.sav, which can be downloaded from chapter data sources referenced above.1- You are interested in investigating if being above or below the median income (medloinc) impacts ACT means (act94) for schools. Complete the necessary steps to examine univariate grouped data in order to respond to the questions below. Although deletions and/or transformations may be implied from your examination, all steps will examine original variables.a. How many participants have missing values for medloinc and act94?b. Is there a severe split in frequencies between groups?c. What are the cutoff values for outliers in each group?d. Which outlying cases should be deleted for each group?e. Analyzing histograms, normal Q-Q plots, and tests of normality, what is your conclusion regarding normality? If a transformation is necessary, which one would you use?f. Do the results from Levene’s test for equal variances indicate homogeneity of variance? Explain. 2- You are interested in studying predictors (math94me, loinc93, and read94me) of the percentage graduating in 1994 (grad1994).a. Examine univariate normality for each variable. What are your conclusions about distributions? What transformation should be conducted?b. After making the necessary transformations, examine multivariate outliers using Mahalanobis distance. What cases should be deleted?c. After deleting the multivariate outliers, examine multivariate normality and linearity by creating a Scatterplot Matrix.d. Examine the variables for homoscedasticity by creating a residuals plot (standardized vs. predicted values). What are your conclusions about homoscedasticity?Please use APA format with references.

Temperature patterns seen to be changing around the U.S. Winters seem shorter, summers seem hotter, and major storms seem more frequent. Let’s collect some data and look at what’s happening in your area. You can use the Weather Underground web page at www.wunderground.com to collect historical data for a particular city. The Weather Underground (www.wunderground.com) was created by a student/professor team at the University of Michigan and shortly became a public company providing current and historical weather data for the United States and other countries. At the top of the Weather Underground home page you will find a box for entering the name of a city, state or country. Enter your home city to see the current weather conditions there. Scroll down and select the History & Almanac Table in which you can enter a date to see statistics for any day from the past thirty years. Below the field where you enter a specific date you can select Calender View and see all temperatures for a specific months.We want to collect the Max. Temperature reading for each day in your home city or a city near you in February (for cold temperatures) and August (for hot temperatures) for a minimum of 3years.
