Submit your work in SPSS by copying the output and pasting into the Word document. In addition to the SPSS output, please include explanations of the results where appropriate. Use SPSS in the same way to answer the questions in Exercise 27 on the full set of data.2. Complete Exercises 6, 8, and 9 in Statistics for Nursing Research: A Workbook for Evidence-Based Practice and submit as directed by the instructor. The objectives are to define basic statistical terms and explain the usefulness of statistics, explain graphical descriptions of data and how a frequency distribution is used to describe a dataset, and calculate descriptive statistics and use them to explain data sets.
