Question

Explain the four-step process that encompasses statistics.

Answer 1

the four-step process that encompasses statistics:

1) data production-

we establish principles of sampling and study design that would be essential in order for us to claim that, to some extent, what is true for the sample should be also true for the larger population from which the sample originated.

Randomization is essential, not only because it prevents bias, but also because it permits us to rely on the laws of probability, which is the scientific study of random behavior.

2)exploratory data analysis-

we learn to display and summarize data that were obtained from a sample. Regardless of whether we had one variable and we examined its distribution, or whether we had two variables and we examined the relationship between them, it is always understood that these summaries applied only to the data at hand

3)probability - probability theory tells us to expect from the values of the sample mean and the sample proportion, given that the corresponding population parameters — the population mean (mu, μ) and the population proportion (p) — are known.

4) inference-

inferring something about the population based on what is measured in the sample is called statistical inference.
