In the specification Unit 4 Topic 5 number 17 it says:

"Describe how to investigate the effects of temperature on the
development of organisms (e.g. seedling growth rate, brine shrimp hatch rates)."

That question about germination has probably got something to do with the effect of temperature on seedling growth rate.

I usually look at the part that comes after.. If a T/U test is formed then difference .if a speamans test is formed then correlation
