Documentation, documentation, documentation. Make sure you document your SAS programs in the SAS program. 1) name datasets and variables with names that really match what they are or they do (if you inherited the variable from another source and did not change it, keep the source name, if you change it at all, change the name) 2) put comments in line in the program between /* */ to explain a) what each steps does b) and why each complex variable is coded the way it is 3) put comments at the top about who programmed the piece of code and when and its purpose 4) put comments at the top which show what changes were made, by who, and why 5) put comments in line highlight which changes were made, by who, and why

Question:

What is the best way to answer word problems?

Margaret W.

Word problems challenge many students, but with a careful well thought out process you can be very successful with work problems. 1. Read the problem through quickly to get a general sense of the question. 2. Identify what you are trying to solve for - for example area of a rectangle 3. Write down the general formula you believe will solve this for example height times width = area of a rectangle 4. Identify in the word problem the values you need - for example height was listed as 2 feet and width was listed as 4 feet 5. Write down the formula replacing the values with those you identified in step 4 and solve - for example 2' x 4' = 8 sq ft 6. Always double-check your arithmetic to ensure you didn't make an error 7. Review the problem compared to this formula to verify you have answered the question correctly using the correct values This may seem like quite a few steps, but if you follow them logically they will soon become second nature and flow very quickly. The last two steps will help you avoid turning in results that are not correct.
