Human Bio Cswk help, stat tests

Alright everyone?

Just found out about this site on google and wondered if anyone can help me out with a stat test for my cswk.

 

I have a set of results that goes a bit like this (this is a sample)

 

Potato 1

8.3cm

Shoot: 1.3cm

 

 

 

 

 

 

 

 

 

 

 

 

 

I need to do a stat test for this table, and I have another 5 of them to go.

I dunno if I have to use a t-test, spearmans rank or what.

 

I'd be very greatful if anyone could help out

The below is just a short insight into what my cswk was about:

 

The cswk was an investigation into how the amount of starch in a potato varied from different lengths from the potato shoot.

 

I let the potatoes grow for a week for the shoot to grow and then took a core bearer and withdrew a core from the shoot down into the potato, then cut discs off this core at different lengths.

 

I reckoned that the amount of starch would increase further away from the shoot.
