Stats t-value interpretation

Hi, I am having trouble interpreting the t-values of my stats test

I have two groups

group 1 - Large companies
group 2 - small companies


for eg. when I run my t-test using SPSS it generates:
t-value = -2.5
sig = 0.03

the significance I have no problem with but the t-value I do


since the t-value is negative can I say that the t-value favours group 2

or do I say the negative value the t-value favours group 1
?

It  depends whether larger or smaller means of whatever you were measuring are considered more favourable to the group
and whether you took mean of group 1 - mean of group 2 or mean of group 2 - mean of group 1

sorry I dont quite get what you are saying...

the way I set it up was that i studied large vs small companies

so my group 1 was means of large companies
my group 2 was means of small companies

ozoCommented:
were the values that you were taking the means of things that companies would want to maximize, or things that companies would like to minimize?
did you compute your t-value by subtracting the large company means from the small company means, or by subtracting the small company means from the large company means?
