1) One or two tailed hypothesis (one tailed = directional, two tailed = non directional)
2) Number of ppts (N=) or degrees of freedom (df)
3) Level of significance
4) Identify the observed/ calculated value
5) identify the critical value
6) Interpet the findings
What tests need the calculated value to be equal or less than the critical value?
Sign test
Mann Whitney U
Wilcoxon
What tests need the calculated value to be equal to or more than the critical value?
Chi quaked
Spearman’s Rho
Unrelated t test
Related t test
Pearson’s r
What is the writing structure for interpreting stats tests?
state critical value due to p value being …., a ….. tailed hypothesis were N/df = .
The calculated / observed value ( ) must be …… than the critical value ( ) to be significant.
In this case the results are …….. and we accept the ……. Hypothesis and reject the ……
So there is no significant difference/ relationship between …….
