Topic 2 DQ 1 Random sampling
Random sampling is important because it reduces time and cost of counting or measuring something in its entirety such as a large part of the population, a specific type of tree, or a specific breed of animal. Random sampling is also preferred for its ability to help reduce bias. A true random sample would be hard to obtain because all parts of the population need to be represented. Simple random sampling is achieved by random selection of members from the sampling frame. The random selection can be accomplished many different ways, the most common being a computer program to randomly select the sample (Grove & Cipher, 2017). Having a computer to randomly select the sample is great but is the computer going to be able to tell if any of the participants are on vacation, out of the area on business, or if they have language barriers and these are just some of the complications that could present a problem in the random sample. Another problem and/or limitation that could prevent a truly random sample is having too small of a random sample to use for a study of a large populous. Having too small a group to study will not show accurate data for a large populous. A way to prevent some of these complications would be to have an appropriate sized study group for the random sample, and to ensure that all parts of the population or demographics are represented.

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.
