1

parametric tests

compare means of groups

assumes that data are numeric and that data is random with a gaussian distribution of variables

2

one sample t test

comparing group mean with a reference value

3

independent sample t test

comparing means of 2 groups

4

paired t test

all participants measures pre and post intervention, compare means

5

one way anova

compare means of >2 groups
p value, post hoc

6

repeated measures anova

all participants tested under >2 conditions/times (ie ROM at 0,3,6 weeks)

7

2 way anova

Main effects: A,B
Interaction: AxB

difference in means according to 2 or more factors

or difference in means among 2 or more groups with repeated measures (interaction btw time and factor)

8

interaction

differences in the effects of one variable according to the level of another

9

non parametric tests

parametric assumptions not met, non gaussian dist

10

parametric independent test

two sample t test

11

parametric paired

paired t test

12

non parametric independent

mann whitney U

13

nonparametric paired

wilcoxin signed rank

14

assessment of linear correlation

p value: is there a correlation?
r value: how strong?
.75= excellent
