How to convert Excel values into buckets?

Question

I have a set of data in Excel and in one column is a estimate (number of weeks)

I want an Excel formula to bucket it into

• Small
• Medium
• La

Answer 1

I prefer to label buckets with a numeric formula. If the bucket size is 10 then this labels the buckets 0,1,2,...

=INT(A1/10)

If you put the bucket size 10 in a separate cell you can easily vary it.

If cell B1 contains the bucket (0,1,2,...) and column 6 contains the names Low, Medium, High then this formula converts a bucket to a name:

=INDIRECT(ADDRESS(1+B1,6))

Alternatively, this labels the buckets with the least value in the set, i.e. 0,10,20,...

=10*INT(A1/10)

or this labels them with the range 0-10,10-20,20-30,...

=10*INT(A1/10) & "-" & (10*INT(A1/10)+10)
