Suggested for low rates of BX
What is scored interval IOA
400
time between 2 successive responses
What is inter response time (IRT)
500
The extent to which the experiment shows convincingly that changes in the BX are a function of the IV and not the result of uncontrolled variables
What is internal validity
500
