Design
* Independent groups design
* Sample Size: 20 participants
Mann-Whitney U
- Independent groups design
- Not normally distributed data as sample is less an 15/group
Why do you use mean as a central tendency?
Because there are no outliers
Why do you use median as a central tendency?
Because there are outliers
Where you are giving your “opinion/rating” =
Ordinal
Where you are stating a “measured” variable e.g. time =
At least interval
Note:
Independent groups design means
two names = Mann-Whitney
