Could anyone tell me how to normalize one factor?

[merrycherub]

Like, if I want to normalize the age factor to calculate gender factor...

for each age, there is a factor value, should I take the overall average of all ages to do the normalization? feel not comfortable to do so...

age 0: 1.7
age 1: 1.5
age 2: 1.4
age 3: 1.3

F: 1.3
M: 0.9

If I need to normalize gender factor, should I just divide 1.3 and 0.9 by the average age factor?


Thanks a lot
