Explain the need to use sampling techniques to make population estimates when total counts cannot be made?

Sampling techniques are used to make population estimates because it is often impractical or impossible to count every individual in a population. By selecting a representative sample, statisticians can make accurate estimates of the entire population. This helps in reducing time, cost, and resources required for conducting a census of the entire population.

What is systematic sampling use for?

In practice, systematic sampling is used on account of its simplicity and convenience. It's easy to explain to the people doing the actual work. It can be justified theoretically wherever the population from which units are to be sampled systematically are randomly distributed. It can be used for sampling households, sampling callers on a telephone line, sampling plants along a transect in (say) a field, sampling people passing through customs, and so on.

How do you explain the meaning and purpose of a sampling frame in random sampling?

The term "sampling frame" may have no meaning at all in "random" sampling, since the "frame" by nature sets the parameters of the sampling, thus rendering the sampling somewhat "non-random". Having said that, you might want to study the quality of corn in your area and, depending on which aspects or determining factors you are studying, you might set your sampling frame as "all the farmers in Waterloo region" or "all the farmers in a particular area growing Gold Harvest F1 Hybrid". These two examples will obviously give you different results as they are intended to study different aspects of corn.
