Question

If a Behavior Technician watched Jimmy for 5 minute periods and recorded if he were humming for ANY part of that 5 minutes period, she would be using:

Answer 1

The Behavior Technician would be using partial interval recording to observe Jimmy's humming behavior. For measuring hummingbird wing beats, the scientist should use seconds and likely milliseconds, marked with the metric prefix 'milli-', to achieve precise measurement.

Step-by-step explanation:

If a Behavior Technician watched Jimmy for 5 minute periods and recorded if he were humming for ANY part of that 5 minutes period, she would be using a form of interval recording called partial interval recording. This observational method is used in various scientific studies, including behavioral studies in biology and psychology. The technique involves noting the occurrence of a specific behavior within a predefined time frame, regardless of how many times the behavior occurs or how long it lasts.

For the hummingbirds' wing beat measurement, the scientist should use the fundamental unit of time, which is the second. Since hummingbirds can beat their wings more than 50 times per second, the factor of 10 the scientist is likely to use to describe the motion precisely would be a smaller unit, milliseconds (ms). The metric prefix that corresponds to this factor of 10 typically used for milliseconds is milli-, which denotes one-thousandth of a second.
