A main con of momentary time sampling is that much of the behavior of interest is missed or uncounted. To avoid this problem, you should keep the intervals short and observe the target behavior frequently
True
List the 3 indicators of trustworthy measurement
Validity, accuracy, reliability

Planned Activity Check (PLACHECK) is a variation of partial interval recording in which you observe a group of students ( and, at the end of each interval, count the # of students engages in the targeted activity, and record the total # of students in the group).
What is true
List the 4 fundamental properties of behavior change:
data points, level. trend, variability
Horizontal axis
Abscissa, x - axis
_______ minimizes measurement bias
a naive observer
