+
+title1
+'Research Question:What are the top three members that had the highest annual income?'
+;
+
+title2
+'Rationale: This should help identify three members that earn the most annually'
+;
+
+*
+Methodology: Use PROC PORT to sort the annual income in the combined dataset 
+descendingly and use PROC PRINT to output the top 3 member id accordingly.
+
+Limitations: The highest top 3 annual income data are not visualized.
+
+Follow Up: We can add PROC SGPLOT statement to plot a bar graph, making the annual 
+income differences more explicit.

+
+title1
+'Research Question: What is the average loan amount for each state?'
+;
+
+title2
+'Rationale: This shows the lending situation from each state.'
+;
+
+*
+Methodology: Use the PROC MEANS statement to compute the mean loan amount.
+
+Limitations: We cannot know the distribution of the loan amount for each state.
+
+Follow Up: Add min, median, and max in the PROC MEANS statement to compute the 
+five-number summaries.

+
+
+
+title1
+'Research Question: What is the purpose of the highest loan amount?'
+;
+
+title2
+'Rationale: This would help identify what is the use of the largest amount of money borrowed.'
+;
+
+*
+Methodology: Use PROC SORT statement to sort the loan amount descendingly and find
+out the purpose of it.
+
+Limitations: The currency symbol for the loan amount is not clear.
+
+Follow Up: Use PROC FORMAT to add dollar sign in the data output.
