Choosing an Inferential Statistical Test Flashcards
What are statistical tests used for?
To determine whether a significant difference or correlation exists
What is the calculated value?
The result obtained from the statistical test
How is the critical value calculated?
From a table of probability values
What is the critical value?
The numerical boundary that stands between accepting or rejecting the null hypothesis
What does an R in the name of the statistical test mean?
The calulated value has to be greater or equal to the critical value for the result to be significant
Reject null hypothesis
What does it mean if there is no R?
Calculated value has to be less or equal to the critical value for it to be significant
What are the three factors in choosing an Inferential test?
Design
The level of data
Difference/ Correlation
What are the three types of design?
Independent groups
Matched pairs
Repeated measures
What are the three levels of data?
