Negative mean statistics in cluster. How do i interpret?

[herzizza88]

Am a newbie here:

I did a data transform in my data with a code provided by my school and ran an automatic cluster analysis on my data. The mean statistics churned out negative mean statistics. I am not sure if that is right at all and how to i interpret this. Pls see image.

here're some bg:

LGT_TBM = LOG(CNT_TBM/(CNT_TOT – CNT_TBM))

CNT TBM: Count of traditional transactions

CNT TOT: Count of total transaction

Why do you think the mean of a variable cannot be negative?

It is not that i think it cannot be negative. I dont know what it means. How do i interpret it or read it?
