VSP 7.0 Review
Sampling is taking a few items from a population that fairly represent the population to obtain information about the population from them. It is usually one of the key steps in research because it determines the validity and reliability of research results. This crucial yet arduous task in research has led statisticians and software developers to create software that can ease this process for many researchers in various fields of study. An example of such a sampling software is the Visual Sample Plan version 7.0 (VSP 7.0).
Definition and Characteristics
VSP 7.0 is a research sampling tool created to help researchers identify the number of items they need from a population to form a sample and the locations of these sample

The installation of the software is easy. One only needs to download the free software's setup file; run it, and follow the simple installation instructions on the monitor. The VSP 7.0 does not create a desktop icon during installation. This occurrence makes its access difficult after installation, especially for those who are not computer savvy. It requires one to access the Start menu followed by the Program Files section to access the program.
Usability
Maps and Sample Areas
The primary purpose of VSP 7.0 is to help a researcher identify the number of sample items needed for a study and where these sample items are located within the study area (Matzke et al., 2014). The first step in using VSP 7.0 is creating a study area by either drawing a map of the study area using tools under the Map icon or loading a map of the study area, which must be in the SHP file format or the DXF file format. Additionally, one can obtain a map of the study area by accessing it from the internet using the Map icon of the software.
The process of loading a map in SHP or DXF file format is easy and often successful. Additionally, obtaining maps from the internet by using the software is easy and often successful. One needs only to type the name or location of the sample area in a dialogue box and the software to obtain the map of the site where the sample area is present provided one's PC has an internet connection. The biggest problem with
this study is the use of convenience sampling, as previously mentioned. Black et al. (2000) make
The researchers used purposive sample but did not give any explanation as to why this choice sampling was made. It is essential to describe the sampling process in a research where this facilitates the reader to distinguish any bias in the whole sampling process. In studies using participants, the process of how to select, access, inform and retain research participants requires considerable thought. Sampling is a key issue, because it is
With these maps, the data could be used by the police for visualization ideal for the public release of unlike information such as planting trees, building new schools, applying for a liquor license, and any other material that might be a concern of the
According to Schutt (2008), sampling is defined as a subset of population used in a study to be a representation of the population as a whole. My final project is a pre-hire assessment which analyzes potential risky pattern behaviors and emotions in the work place. One of the most important considerations related to sampling that will need to be addressed in my final project is defining the population that will be taking the assessment.
Probability sampling, also known as random sampling, requires that every member of the study population have an equal opportunity to be chosen as a study subject. For each member of the population to have an equal opportunity to be chosen, the sampling method must select members randomly. Probability sampling allows every facet of the study population to be represented without researcher bias. Four common sampling designs have been developed for selection of a random sample: simple random sampling, stratified random sampling, cluster sampling, and systematic sampling (Burns & Grove,
Since the Institute of Medicine’s widespread reports, To Err Is Human (2000) and Crossing the Quality Chasm (2001), revealed widespread incidence of medical errors in U.S. hospitals, there has been a great deal of effort to measure and improve the quality of hospital care. Progressive input has been made in establishing quality indicators and risk adjustment components to compare quality across organizations, and in analyzing processes and cultures in high-performing hospitals. There is a vast amount of knowledge to learn about the infrastructure of hospital performance. Health care organizations performance measures may include which hospitals are
When analysing the CASP tool which is used in this essay, it has 10 different questions and each question
I believe that Kudler’s Fine Food has an excellent opportunity to expand its gourmet specialty food store by adding a delivery service. An upscale store should provide upscale service, which will expand Kudler’s Fine Food services enormously. Being that the number one strategic objective of Kudler’s Fine Food is to expanded its services, this will surely accomplish this objective.

Sample (sampling techniques, sample size, sample characteristics) Two authors independently reviewed the references to identify studies for inclusion and extracted data to assessed risk of bias in all included studies.
When conducting a study, it is impossible to collect data from the whole population, therefore it is important to select a representative sample because sampling makes it possible to select a representative for study and discover things that apply to many more people who are not studies (Maxfield & Babbie, 2012). The purpose of sampling is to generate a set of individuals or other entitles that give us a valid picture of all such individual or other entitles. It is important to generalise from a sample to unobserved population the sample in intended to represent. Therefore, when selecting a group of subjects for study, it is important to ensure that we represent some larger population.

According to Hair et al. (2003), in the research, the sampling process enables identifying, developing and understanding an interested object that need to be determined (p.333). Hence, in order for the researcher to carry out the sampling appropriately, advantages and disadvantages of the various sampling methods should be considered along with the theoretical component of the study (Hair et al. 2003, p. 368 f). Theoretically, the sampling procedure is divided into two major types which consist of probability and nonprobability sampling. In probability sampling, individuals have a known chance of being selected. While, in non-probability sampling, individuals do not have a known possibility to be selected (Sekaran 2003, p. 269 f). Also, the different sampling methods provide different advantages and disadvantages. Hence, the researcher should consider this point before choosing the sampling method for the
