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.
Sampling has several disadvantages. These include time consuming and tedious. Possibly, members of units are different from one another, thus decreasing its effectiveness.
You do not have all the information and so your conclusions are based on approximations.
Mostly can be biased and in some cases can choose people/units innapropriate for the circumstances
1).There may errors (Producer's and Consumer's risk) associated with the sampling. 2).The sample does not provide 100% accurate information of the condition of the bacth.
advantages: reduce bias easy of sampling disadvantages: sampling error time consuming
advantage of probability sampling

please help!
used for a smaller population

avantages and disadvantages of mixed sampling are explained by example given below : if we want to take sample of trees in the forest of India for this we will selected the forests by the simple random sampling and after this we will selected the trees by the systematic sampling we can not used simple random sampling here due to not availability of frame of trees.So this is adavantages of mixed sampling. Now if we want to check the relability of whole procedure then we will not check it .So this is disadavantages of mixed sampling.
