Me, Myself and I 3 Flashcards
1
Q
when are we more inclined to believe the data diverges from the null hypothesis
A
if the p-value is very small
2
Q
what is the p-value
A
the probability that we would have observed a given derivation if the null hypothesis was correct
3
Q
what must a statistically significant p-value be
A
0.05 or lower
4
Q
what are type 1 and type 2 errors
A
type 1:false positives (p-value of 0.049)
type 2:false negatives (p-value of 0.051)
5
Q
what is the purpose of measuring effect size
A
helps researchers assess the magnitude of an effect
6
Q
if a type 1 or type 2 error is found what is often wanted
A
more data or research since the p-value is close to the acceptable value
