Question 1a)Apply the necessary transformation in PSPP/SPSS using the relevant variables from the datafile to create two new variables, 1) Number of Days in the Month and 2) Decade. Identify the appropriate scale of measurement for both variables, and generate the frequency distribution tables for both variables. Cut and paste the PSPP/SPSS outputs into your answer.Note: For Number of Days in the Month, please remember to take into account leap years. Note: For Decade, please use the 0-to-9 decade denomination to group the yearsb)Apply PSPP/SPSS to examine the appropriate descriptive statistics and graph(s) for Total Rainfall separately by Months of a Year, Yearly, and Decade. Interpret the results in terms of the appropriate descriptive statistics and identify the Month(s), Year(s) and Decade(s) with the highest and lowest Total Rainfall.Note: Please cut and paste your PSPP/SPSS output into your answer to demonstrate that you have used PSPP/SPSS. Note: The appropriate descriptive statistics might differ for Months of the Year, Yearly or Decade
