Learn in Detail About the Different Methods of Sampling
Sampling is basically a part of statistics. Selecting a set of aspects within a population of statistics to understand or estimate the standardized characteristics of a selected population is termed as sampling. The main reasons for which sampling s carried out are that it has low cost involved and secondly it saves time because we do not consider the whole population. We provide guidance to students studying sampling at our portal for sampling homework solutions.
The different methods of sampling
Depending on different aspects like cost, amount of detail required, requirement of accuracy, information available, nature of frame to be sampled, there are various methods of sampling that are utilized. Details about all such methods can be learnt from our sampling assignment solutions portal. Few such methods have been mentioned below.
Sampling that involves probability according to size
This is the type of sampling where probability of a variable is sampled in accordance to its size. In this system, each element’s selection is related to its measuring size. The only drawback of this sampling method is that its sample size is variable. In this system, portions of a population may be wrongly represented as the system involves variation of selections by chance. Details of the method can be easily learnt by visiting our sampling homework solutions.
Sampling by stratification
This is a system of sampling in which a number of separate categories are considered as separate strata. Each category or stratum is considered a separate sub-population and is sampled accordingly. There is a random selection made after that. The sampling fraction is obtained which is the ratio between the random selection sizes to the actual population size. Learning more about this form of sampling can be easily done by clicking on our sampling assignment solutions service.
Interval sampling
This is another form of sampling which is also known as systematic sampling. In this system there is an ordering scheme according to which the population of study is arranged, this is followed by selection of elements at specific intervals through an ordered list. In this method, it is very essential to choose a proper beginning to the sampling.
Random sampling method
In this method of sampling, all the subsets are given equal importance. This helps to give each element of the frame a probability that is equal. There is no partition or division to the sampling frame. This system is very prone to getting errors because of the selection process being random.
