I am looking at a query that will help me represent the distribution of data records based on the column answer. For example, we may take that the highest entry for answer column is 90 and the lowest is 2 and there are 1000 records. I am looking at a query that will tell how the 1000 records are distributed between the highest and lowest answer (in this case between 90 and 2). Can anyone please help?
