Measurement
A-03, A-04, A-05
| Term | Definition |
|---|---|
| discontinuous measurement | some instances of the behavior may not be detected; you aren't observing every occurrence of the behavior |
| discontinuous measurement | estimating the actual occurrence of the behavior, rather than recording every instance |
| partial interval, whole interval, momentary time sampling (MTS) | what are the 3 ways of recording discontinuous measurement |
| direct measurement | behavior is actually observed; it is the same behavior that is the focus of the data collection |
| indirect measurement | interviews or questionnaires |
| partial interval | discontinuous, direct time sampling procedure where a behavior is recorded as occurring, if it occurs at least once during the predetermined interval |
| partial interval | may overestimate occurrence of the target behavior; findings are reported as a percentage rate |
| whole interval | discontinuous, direct time sampling method; a behavior is recorded as occurring if it is observed throughout an entire predetermined interval |
| whole interval | may underestimate occurrence of target behavior; only record the behavior if it occurred entire interval |
| momentary time sampling | discontinuous, direct data sampling procedure when (at the end of a predetermined interval) a recording is made if the target behavior is occurring at that moment |
| momentary time sampling | may underestimate occurrence of behavior; findings are reported as a percentage or rate; you watch to see if the behavior occurred at the end of the interval; if it is occurring at that moment, you would mark that interval |
| permanent product | the things people produce as a result of their behavior |
| permanent product | quiz, written essay, completed project, house built, dinner made, picture taken |
| level | the range between the lowest data point in a set and the highest |
| trend | when you draw a line through the data points that is closet to matching each individual point; defined by the "Pearson's r coefficient" |
| variability | a somewhat subjective measure when evaluated visually; how consistent the data points are to each other |
| variability | when lacking this, a stable pattern is almost completely at the same level, looks like a horizontal line if you connect data points |
| variability | when this is high, it is difficult or impossible to draw the trend line |
| variable data | in a function analysis, this might suggest an automatic reinforcement function |
