Comment 1

Concerning the different methods argued in the “Visual Learner: Statistics,” it is important to abide on the statistical hypothesis. There are two chief types of analysis. They are null hypothesis in which samples apparent result as a result of chance and alternative hypothesis where sample observation is predisposed mainly by non-random causes. There are a total of five sampling techniques that have been discussed with systematic sampling, simple random sampling, cluster sampling, convenience sampling and stratified sampling. Systematic sampling is a type of probability sampling method where the sample members coming from the larger inhabitants are designated based on a preparatory point random as well as a fixed periodic interval.
An example includes when a researcher wants to create a systematic sample in a university of about 90,000 enrolled students, they should consider every 100th student. A simple random sample denotes a set of data where every person has an equivalent probability of being chosen. An example includes selecting 50 members from a set of 400 employees to represent a company in an individual event. Cluster sampling is a sampling method where the population is divided into groups referred to as clusters.
An example would include getting the level of educational performance of high schools in the entire nation. A convenience sample can be categorized among the non-probability sampling methods. It is made up of people who can be reached speedily like business operators in a center and family members. An example includes an interview by a pollster to a purchaser who functions at a local mall. Finally, Stratified sampling refers to a method of sampling where the population effects to be distributed into minor groups that are called strata. The layers are therefore, formed basing the arguments on the shared characteristics and attributes of the members.

The visual learner statistics page includes five different samplings which include cluster sampling, simple random sampling, systematic sampling, convenience sampling, and stratified sampling.
Cluster sampling is dividing the population into sections. The cluster sampling is chosen randomly and it includes all the individuals of that particular cluster that was chosen. An
example where cluster sampling could be used is at area high schools. Many towns have several high schools within a descent range where it could be easy to pick a grade and randomly select a high school.
Simple random sampling allows every member of the study population to have an equal opportunity to be chosen as a study subject. Random sampling is known to eliminate bias by giving the population an equal chance to be chosen. An example where simple random sampling could be at a hospital and involve all register nurses.
Systematic sampling is choosing a larger population and selecting the individuals at a random starting point and a fixed periodic interval, for example picking the every fifth person (Business Dictionary, 2018).  Systematic sampling could be used in a large city of businesses and every fourth street in the district could be selected.
Convenience sampling is just that the convenience of selecting the individuals. Convenience sampling be simply your closet friends or coworkers.
Stratified sampling is choosing a general population that share the same qualities and features and separated them into different groups. An example of using stratified sampling is choosing a group of men and a group of women and dividing them into different groups.
