Hope i'm not too late! I have this one today too,

chi squared = Will your investigation involve finding the number of individuals in particular categories?

(If it involves measurement it will be one of the 2 below)
Standard Error = Will your investigation involve looking for differences between mean values?

Spearmans rank = Will your investigation involve looking for associations between different measurements from the same sample?

Good luck!

Anyone done the Biology Reaction Time IsA
I've done the:
- Biology AS Osmosis and Glucose
- Biology A2 Populations
- Chemistry AS and Chemistry A2 ISAs too.










They've been okay, but not many people seem to have done the reaction time?
