Lecture 10
Alternative options used when violating
assumptions of normality
COPY THIS FOR EXAM?
EXAM CHEAT SHEET
People in only one
condition People are in all conditions
More flexible
As there is more than 2 groups
0 gets a rank of 1 next score gets a rank of 2 ect.
Do this first then worry
about ties after
If there wasn’t a tie again it would just follow
on and be a six as that was the next
potential rank
6+7+8=21
21/3=7
Therefore actual rank is 7
Move on if theres
no tie we can use
the potential rank
11+12=23
23/2=11.5
13+14+15=42
42/3=14
16+17+18=51
51/3=17
No tie can use potential
rank
No tie can use potential rank
As its within (repeated) subjects with
more than 2 groups
Sum of all the ranks
