So I have tested the same species of plant under 7 different conditions.

1 = Control (no fungus)

2, 3, 4 = Fungus A at 3 different concentrations.

5, 6, 7 = Fungus B at 3 different concentrations.

I am going to undertake T-Tests to compare my results.

I just want to make sure I have the tails and type of T Test correct.

I have undertaken a 1 tailed paired T - Test.

(because I want to know if the mean of 1 strain is statistically greater than the other).

Is this correct? I ran an unpaired unequal variance T Test to see if the results are different and it gives me massively different results so I want to make sure I've picked the right test before I start my full write up.
