What is a sample in a TCC? How to define sampling? What is a sample in a survey? Very well, if you have questions about sampling, I will try to answer all your questions in this video. Of course, the topic of sampling is broad and is divided into several categories, but I will try to make a good summary to present to you and help in your studies. Samples are subsets of a population, so when we choose a characteristic to be studied in the population, it is necessary that the sample also maintains these characteristics. A researcher who needs to study a certain population selects a small representative part of it and this small part becomes the representative of that population (this is the sampling in the survey), so that the researcher can study it in the best way.

I thought it was a floating fertilizer bag, but it turned out to be a giant one, blocking the canal.
