Often not, but it is important to check that there is no systematic pattern in the skip.
To take an unlikely example, suppose you wanted to sample the values of 10% of houses on a street with 200 houses on it. A possible systematic sampling scheme would be to select a random house number to start with and then select every 20th house number (looping back when the number exceeds 200). If the first house number is odd then all houses in the sample are odd numbered and, therefore, on the same side of the street. If the street runs East-West, the sample could consist exclusively of South-facing gardens - attracting a price premium!
They include: Simple random sampling, Systematic sampling, Stratified sampling, Quota sampling, and Cluster sampling.
You can't conduct startified sampling if there are no difinative groups, thus systematic sampling is more efficient if your data has no groups.
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.

Random sampling is picking a subject at random. Systematic sampling is using a pattern to pick subjects, I.e. picking every third person.

Compare the efficiency of simple random sampling with systematic random sampling for estimating the population mean and give your comments.

Answer is Quota sampling. Its one of the method of non-probability sampling.
Sampling error leads to random error. Sampling bias leads to systematic error.
