Is “knowing each item in the population” important in random sampling?
It was helpful ??thank you very much,but please if the answers would be shown after the test it will be nice *
The answers are shown if you click on the ‘review quiz’ button after having submitted your answers!
is “knowing each item in the population” also important in systematic sampling?
No, because we would be selecting every n’th item regardless of what was the case in the population as a whole.
Could you please explain what is population data and what is continuous data?
The population is all the items in the particular category (out of which we take a sample).
Continuous data is explained in the lectures on Measures of average and dispersion.
Question 3
How is the knowledge of each item of the population true of Stratified sampling ?
You have to know what proportion of the population are in each group in order to know what proportion of each group to sample.
Question 2. Why is not multistage sampling, although there is no such answer to choose?
Because taking every 20th item is systematic sampling, not multistage sampling.
See the explanation of both in our free lectures notes and the free lectures that go with the notes.
Now I noticed the tricky moment in the question, it starts just pocking 12th iteam, NOT each 12th iteam.
Thank you for the help, sir
You are welcome 馃檪
