-Within
-Ordinal data
-Purpose is to test if the scores on two separate variables vary proportionately. - 7Chi SquareNon parametric
Between
Nominal data
-to test if the no. of pp's in one category is significantly different from the no. in another. - 8McNemarNon parametric
Between
nominal data
-To test if the no. of pp's in one category is significantly different from the no. in another. - 9Type 1 ErrorThe null is rejected when it should be retained.
Conclude that there IS a significant difference when there is NOT. - 10Type 2 ErrorNull is retained when it should be rejected.
We can conclude that there is NO significant effect when there IS.
