For example, a researcher may observe a group of children for 10 seconds every 5 minutes for a specific ...The time between 2 consecutive /DONE signals (e.g. conversion complete interrupt) is the same as TRIG signal because the added sampling time is fixed. as long as TRIG interval is bigger than sampling time (+ instruction processing wasted time). Sampling time is usually used as a limiting value (or a fine tune):Advantages of Time Sampling. - gathers info on all the children in the class at one time. - give quantitative info about attention span ("Cindy spent ___ minutes at the easel) - indicates the child's play/interest. - gives clues to child's strongest/less developed areas (inferred by choices/avoidances) - indicate the stage of play the child is in. Event sampling methodology (ESM) refers to a diary study.ESM is also known as ecological momentary assessment (EMA) or experience sampling methodology.ESM includes sampling methods that allow researchers to study ongoing experiences and events by taking assessments one or more times per day per participant (n=1) in the naturally occurring social environment.
Multistage sampling is flexible, cost effective and easy to implement. You can use as many stages as you need to reduce the sample to a workable size, with no restrictions on how you divide the groups. However, as the method has a subjective component, it has problems with external validity. It is also less accurate than simple random sampling.

In signal processing, sampling is the reduction of a continuous-time signal to a discrete-time signal. A common example is the conversion of a sound wave to a sequence of "samples". A sample is a value of the signal at a point in time and/or space; this definition differs from the term's usage in statistics, which refers to a set of such values.
