What does probability estimate?
Percentage chance of an
event
occurring
View source
How is probability expressed in psychology?
As a
decimal
, not a percentage
View source
What is the purpose of calculating probability in psychology?
To estimate the likelihood of results being due to
chance
View source
What is the traditional accepted level of significance in psychology?
P
≤
0.05
View source
What does it mean if the probability of results being due to chance is less than or equal to 5%?
You accept the alternative hypothesis and reject the
null
View source
What happens if the probability is more than 5%?
You reject the
alternative hypothesis
and accept the
null
View source
What is the process to determine if findings are significant in psychology?
Calculate the
probability
of results due to chance
Compare the probability to
P
≤
0.05
Accept or reject hypotheses based on the comparison
View source
What does it mean if findings are significant at P ≤ 0.05?
Observed value is higher/lower than
critical value
View source
What is the critical value used for in hypothesis testing?
To determine
significance
in results
View source
What does a one-tailed test assess?
Direction
of the effect
View source
What does a two-tailed test assess?
Both directions of the
effect
View source
What does 'n' represent in hypothesis testing?
Sample
size
View source
How do you conclude if findings are significant or non-significant?
By comparing
observed value
to
critical value
