Systematic sampling involves selecting items at equal intervals throughout the period of interest, which helps ensure that items are continuously sampled over that period. This is a better choice than haphazard or random sampling, which may not provide equal representation of items over time. Block sampling involves dividing the period of interest into distinct blocks and sampling from each block, which may not be appropriate if the characteristics of interest change over time.
