Advantage -- Less effort, cost, work
Disadvantage -- Less accuracy, information, difficulty of establishing true 'randomness" in some samplings.

Hi, 1.The main advantage of Systematic sampling over simple random sampling is its simplicity. It allows the researchers to add a degree of system or process into the random selection of subjects. 2.Another advantage of systematic random sampling over simple random sampling is the assurance that the population will be evenly sampled. Disadvantage The process of selection can interact with a hidden periodic trait within the population.
It can interact with a hidden periodic trait within a population hence the technique will be compromised since there will not be random and representativeness of the saple
Disadvantages of systematic sampling: © The process of selection can interact with a hidden periodic trait within the population. If the sampling technique coincides with the periodicity of the trait, the sampling technique will no longer be random and representativeness of the sample is compromised.
Yes, if under simple random sampling there are likely to be too few representatives from a certain subset of the population in which you might have an interest.
a simple random sampling is very difficult to conduct if the size of the population being studied is large. Moreover , it needs a lot of time and money. - S
