Any ideas how to determine what age group an individual belongs in Excel?

Question

I have 2 columns in an Excel spread sheet.

First column header is called AGE and the second column header is called Age_Group.

The ages in the AGE column are bet

Answer 1

Use a vlookup. Create a two column table with the lower bound of your age range in the first column and the age range as text in the second column like so:

AGE_LOOKUP  AGE_GROUP
18          18-24
25          25-29
30          30-35
36          36-37 etc..

Name this table's range as AGE_GROUP_TABLE then using the following formula to get the age group:

VLOOKUP(A1, AGE_GROUP_TABLE, 2, TRUE)

Put different ages into cell A1 and the formula will return the correct age group. The important thing to remember is to make sure that the last parameter of the VLOOKUP is set to TRUE, this makes the VLOOKUP find the nearest match.
