Topic 2 DQ 1 In an experiment or research
In an experiment or research where it is imposable or expensive to sample the entire population, a small sample is used to conduct the research. A sampling method is the process of selecting a small group that are representative of a larger population being studied. Samples can be made in different ways. All these ways are not equally good. Most studies a random sample is used for this reason. A random sample selected in such a way that every member of the population has an equal chance of being selected (Fraenkel & Wallen). A random sampling method is designed to select a representative sample by using chance selection so that biases will not systematically alter the sample (Fraenkel & Wallen). A true random sample, that is a small set of data can give insights which can be applied to a much larger group. Simple random sampling is achieved by random selection of members from the sampling frame(Grove & Cipher, 2017).
Example; When Joint commission come for inspection to the unit, they pick one RN to interview randomly. Every nurse who work on that floor has the same chance being selected for the interview.
A sample group is used to conduct research or study there is always a chance for error because it can never fully match the entire population. It can be prevented by;
Researchers should strive to ensure that the sample population truly represents the total population. Statistical tests have built in checks to ensure true sample and the numbers can only be an estimate

You must proofread your paper. But do not strictly rely on your computers spell-checker and grammar-checker; failure to do so indicates a lack of effort on your part and you can expect your grade to suffer accordingly. Papers with numerous misspelled words and grammatical mistakes will be penalized. Read over your paper in silence and then aloud before handing it in and make corrections as necessary. Often it is advantageous to have a friend proofread your paper for obvious errors. Handwritten corrections are preferable to uncorrected mistakes.
Use a standard 10 to 12 point (10 to 12 characters per inch) typeface. Smaller or compressed type and papers with small margins or single-spacing are hard to read. It is better to let your essay run over the recommended number of pages than to try to compress it into fewer pages.
Likewise, large type, large margins, large indentations, triple-spacing, increased leading (space between lines), increased kerning (space between letters), and any other such attempts at padding to increase the length of a paper are unacceptable, wasteful of trees, and will not fool your professor.
The paper must be neatly formatted, double-spaced with a one-inch margin on the top, bottom, and sides of each page. When submitting hard copy, be sure to use white paper and print out using dark ink. If it is hard to read your essay, it will also be hard to follow your argument.
