Given below are two statements. In the light of the above statements, choose the most appropriate answer from the options given below:
Statement I:In systematic sampling, one can choose units directly from the sampling frame, without opting for a table of random numbers
Statement II:The simple random sample is the most primary form of non-probability sample
ABoth Statement I and Statement II are correct
BBoth Statement I and Statement II are incorrect
CStatement I is correct but Statement II is incorrect ✓ Correct
DStatement I is incorrect but Statement II is correct
Correct answer: (C) Statement I is correct but Statement II is incorrect
Explanation
Systematic sampling can indeed draw units straight from the frame, but calling simple random sampling a non-probability method is wrong.
Statement 1 is true, as systematic sampling picks every kth unit from the frame without a random number table.
Statement 2 is false, because the simple random sample is the most basic form of a probability sample, not a non-probability one.
In a probability sample every unit has a known, non-zero chance of selection.
Non-probability samples include convenience, quota and snowball sampling.
Systematic sampling only needs a random start and a fixed sampling interval.
