whether the method of
measurement being used
measures what it is supposed
to measure

. #TrueValue

Answer 23

Accuracy

Question 24

This refers to repeated contact
and getting the same

Answer 24

Reliability

Question 25

This allows the measurement of the behavior after it has occurred by measuring the eects the behavior produced on the environment

This is the degree to which a study’s results are generalizable to other settings, subjects and behaviors

Answer 26

External Validity

Question 27

This refers to the extent to which an experiment shows the changes in behavior are a direct result of the independent variable and not the result of uncontrolled variables.

Answer 27

Internal Validity

Question 28

This refers to the extent to which an experiment shows the changes in behavior are a direct result of the independent variable and not the result of uncontrolled variables.

Answer 28

Interobserver Agreement (IOA)

Answer 31

Exact Count Per Interval IOA

Question 32

This is the simplest method for calculating IOA using event recording data

Answer 32

Question 33

This type of IOA uses the intervals in which one or both of the observers scored that a behavior has occurred.

Answer 34

always wrong

Question 35

Meg the Stallion is studying for her next degree. Her and her bestie take data on the number of questions she gets correct per minute.

No, because doctor's scale is considered #true value
