Solve Designing Samples

Introduction:
Probability and non-probability samples are used to prepare the designing samples. In these two types some other small types of samplings are used to designing samples. Such as simple random sample, stratified random sample, cluster sample, systematic random sample, multi stage sample and convenience sample, volunteer sample, judgment sample etc. Let us discuss and solve designing samples in this article.
Probability Samples:
A probability sampling system is for any sampling which utilizes some appearance of random selection. Probability samples are used for finding the sample population. Here we will see what are the types in probability samples.
Simple Random Sample: All the individuals have an equal likely possibility to choose the samples. It is similar for each and every sample size of n.
Stratified Random Sample: Stratified random sampling is also called as proportional random sampling. This is a probability sampling method in which the subjects are primarily grouped into different classifications. For example age, socioeconomic status or gender.
Cluster random Sampling: ...
... Cluster random sampling is completed while simple random sampling is nearly not possible to the size of population. Population will occur in a normal group. Groups will be selected randomly. Every individual within the randomly selected group becomes the part of sample.
Systematic Random Sampling: Population is classified into groups of same size. The number of groups is similar to the sample size. Here one person is chosen from the first group.
Multi Stage Sampling: Most of the researches are completed in different stages with every stage applying a special random sampling method. These are the types which are used to prepare the designing samples.
Non-probability Samples:
To prepare the designing samples we want convenience sample, judge sample and volunteer sample. Here we will see the non-probability samples for solve designing samples.
Convenience Sample: The member in a convenience sample is convenient to the researchers. They can or can not correctly reproduce the population of concentration. We can not be able to simplify the information composed from this sample to the future population.
Judgement Sample: The researchers must choose the individuals for the trial. These types of trials are only as excellent as the researcher’s judgment.
Volunteer Sample: Sample provided by involved parties; a partial sample because this does not denotes all divisions of the population and it is known as self-selection.
Example Problem:
Example: The expected frequency value is 5% (0.05) Find out the sampling results.
Solution: The expected value = 5%.
`N = (t^2 * p (1-p)) / m^2`
`"= (1.96 * 0.0.05 (1-0.0.05)) / `
`= 0.931`
