Can you think of time when only one baseline data point would be sufficient?

Yes! Usually
Do behavior analysts like measuring stuff?

Not sure but it must be pretty fast.

Involves measuring the length of time from the deliver of an antecedent stimulus that should elicit the target behavior, to the actual beginning of the target behavior.
What is latency recording?
200
Select a time period; divide the period into equal intervals, and record if the behavior was observed at the END of the interval.
How do you do time sampling?
200
Involves measuring the length of time from the delivery of an antecedent stimulus that should elicit the target behavior, to the actual beginning of the target behavior.
What is latency recording?

Generally, if 80-90% of the data points fall within a 15% range of the largest data point values of a condition, consider the data stable
When determining stability there is not mathematical formula but...

Most accurately reflect the number of times a behavior occurs. Method of choice when objective is to increase or decrease the number of times a person engages in a specific behavior. Used for discrete behaviors (i.e., those that have a clear beginning, middle and end). NOT good for behavior so high in frequency that it is hard to count.
What is event recording?
300
Rate (frequency)=count/observation period
What is the most commonly used measure based on repeatability?
300
80-90% of the data points fall within a 50% range of the largest data point.
What counts as a stable baseline?
300
Ascending (upward), descending (downward) or variable trends.

1. To see if the behavior is at a level that needs to be changed. 2. To serve as a comparison (baseline to treatment) to evaluate efficacy of treatment.
Why do we take repeated measures of baseline data before starting treatmen?
400
A time sampling method for measuring behavio in which the observation period is divided into a series of brief time intervals (usually 5-10 seconds) The observer records whether the behavior occurred at any time during the intervval. Partial-Interval recordin is not concerned with how many times the behavior occurred during the interval or how long the behavior was present, just that it occurred at some point.
Define partial interval recording.
400
MTS=a measurement method in which the presence or absence of behaviors are recorded at precisely specified time intervals. Planned activity check (PLACHECK) A variation of momentary time sampling in which the observer records whether each person in a group is engaged in the target behavior at specific points in time; a measure of group behavior
What is the difference between momentary time sampling and PLACHECK?
400
Momentary time sampling for groups (e.g., number of students on task)
What is PLACHECK?
400
Whole interval, partial interval, momentary time sampling
Name 4 types of time sampling

When the length of time that the behavior occurs is the primary concern rather than how often the behavior occurs.
When is duration recording used?

Ineffective
In terms of effectiveness of interventions, Percentage of Non OverLapping Data Points (PND) scores over 90% are considered very efffective while PND scores below 50% are regarded as
