FAQ
Frequently Asked Questions
Not exactly. Spread sampling is a specific strategy that aims for an even distribution. It can be implemented as part of a systematic random sampling method, but 'random sampling' alone does not guarantee a spread distribution; samples could randomly cluster.
It is frequently used in manufacturing quality control, environmental monitoring (air/water testing over time), agricultural research (testing soil in different field plots), and market research (surveying across diverse demographics).
Yes, this is a very common application. For example, taking measurements at evenly spaced time intervals (e.g., every hour, every week) instead of all at once is a form of temporal spread sampling.
The main risk is sampling bias due to clustering. If all samples are taken from one location, time, or group, the data will not represent the whole population or process, leading to inaccurate conclusions.
