Challenge #3: Running Averages

A little tricky due to NULL values and not grouping by month and year.

I was confused by the moving average example given in instructions...the three numbers given divide by 3 does not equal the moving average supplied as the example answer.

 

Month: Value: Running 3 mo. Average:
1 218 218
2 200 212
3 272 233

 

218+200+272 = 690 / 3 = 230 (not 233)

 

I am fairly pleased with my answer from an eloquence perspective. Would love for someone to give it a look over, but seems to be producing the correct output.

 

Originally was doing multiple multi-row formulas, but the transpose then cross tab approach worked pretty well.

My solution to number 3.  Two joins at the end for clarity of flow.
