parametric data |
paired sample t test - is the difference large enough that it is significant? |
|
|
t tests |
these take the difference between t1 and t2 and uses this data |
|
|
t value |
t value increases as difference increases assuming they increase in the same direction less variation in scores larger score more likely to be significant |
|
|
Cohen's d |
this calculates the effect size in t tests |
|
|
effect sizes (Cohen's d) |
0.2 - 0.5 = small 0.5 - 0.8 = medium 0.8 + = large |
|
|
standard form |
t(N) = t- value, p = 3 dp (1 or 2 tailed), Cohen's d = 2 dp |
