Type 1 And 2 Error Flashcards
1
Q
Type 1 error
A
When researchers incorrectly reject the null hypothesis and say there is a real difference between two experimental groups when there isn’t one
2
Q
How does a researcher minimise type 1 errors
A
By setting their significance levels very low
3
Q
What can a very low significance level increase the chance of
A
Type 2 errors
4
Q
If a researcher has a significance level of 15%,what probability do they have of making a type 1 error
A
15% probability of making a type 1 error
5
Q
Type 2 error
A
When researchers fail to reject the null hypothesis and conclude their results happens by chance when there actually is a difference between two experimental groups
6
Q
To valence the risk of a type 1 and type 2 error we ussaly set the significance level at ?
A
5%
