A behavior is not easily counted when: z It is difficult to tell exactly when the behavior begins or when it ends, or z It occurs at such a high rate that it is difficult to count. Use Momentary Time Sample recording if the behavior tends to last for a while, such as The sampling rate is the frequency expressed in Hertz (Hz) at which the ADC samples the input analogue signal. As mentioned before, the sampling interval is the time between successive samples: the sampling rate is thus the inverse of the sampling interval. Generally speaking, the faster the rate at which a signal changes, the higher the ...

Time samples can be used for children 3 years old and up in group settings.II. Timing and Sampling 1. Time sample: A constant length of time employed for each dis-crete observation of the defined behavior. 2. Distribution of time-samples: A statement as to how total be-havior was sampled according to the time of day, month, or year, the activities engaged in, or the systematic variation of the order of observation for

Time sampling Time sampling is often used where there is a concern about an aspect of behaviour. It involves observing a child for an extended period such as a whole morning/afternoon session, or even a whole day.The sampling rate is the number of samples per second. It is the reciprocal of the sampling time, i.e. 1/T 1 / T, also called the sampling frequency, and denoted Fs F s. The frequency axis for the FFT is linked to the number N N of points in the DFT and the sampling rate Fs F s. It is defined as f = k ⋅ Fs N f = k ⋅ F s N.
