statistical tests Flashcards
1
Q
Nominal data
A
Categorical data
2
Q
ordinal data
A
Data that has been ordered and the intervals between the data are not equal
3
Q
Interval data
A
Data that has equal intervals between each unit
4
Q
Tests of difference when it is ordinal data
A
- wilcoxn
- mann-whitney
5
Q
Wilcoxn
A
- ordinal data
- used for repeated measures or matched pairs
- calculated value must be equal to or less than the critical value
6
Q
Mann- whitney
A
- ordinal data
- used for independent groups design
-calculated value must be equal to or less than critical value
7
Q
Tests of difference for nominal data
A
The sign test
Chi squared test
8
Q
The sign test
A
- nominal data
- used for repeated measures design or matched pairs
- used for difference between paired data
- significant result - calculated value must be equal to or less than the critical value
9
Q
Chi squared test
A
- used on nominal data
-Degrees of freedom = (rows -1) x (columns - 1) - DF = Calculated value
-significant value = calculated value must be equal to or greater than the critical value
10
Q
Tests for association
A
- Spearmans rho
- Pearsons R
11
Q
Spearmans rho
A
- Ordinal data
- Significant answer = the calculated value must be equal to or greater than the critical value
12
Q
Pearsons R
A
- interval data
- test of correlation
- significant result = the calculated value must be equal to or greater than the critical value
13
Q
Tests of difference for interval data
A
- related T test
- unrelated T test
14
Q
Related T test
A
- Repeated measures or matched pairs design
- interval data
- Significant value = Calculated value must be equal to or greater than the critical value
15
Q
Unrelated T test
A
- Data from independent groups design
-Degree of freedom = ( ppts in con A ) + (ppts in con B) - 2 - DF = calculated value
Significant value = calculated value must be equal or greater than the critical value
