Your final project entails systematic extraction of decision-aiding insights out of dataset (Sample DataSet.xisz) provided to you in the Doc sharing area. In this section, you will carry out the following basic estimation and tests of differences using the provided tendency, spread) as well as graphically. Compare the results. (1) Identify three continuous and three discrete variable and describe their distribution numerically (e.g. central tendency, spread) as well as graphically. Compare the results. (2) Using the variables selected, conduct all possible test t-tests and chi-squared tests. Describe your findings. In addition, discuss how data limitations (e.g., missing values, etc.) can affect the validity and reliability of statistical estimations and tests of differences. Be specific. Show your work using Microsoft Excel and import your work into a Microsoft Word document. Submit your response with imported Microsoft Excel work in a 3-4 page Microsoft word document.
