Lower cost, greater accuracy of results, greater speed of data collection, and availability of population elements are all reasons to sample, p. 338. “Samples depend on rules for the selection of the sample but provide benefits such as being able to measure the precision of the sample from the sample units themselves,” states Bailar, p.47. This will allow for analysts to say that results are not statistically significant because of the difference in measurements from different times. Sampling should allow all questions, as stated in the company’s goals, to be answered. It will be a detailed outline that will include what times the measurement will be taken, on which material, in what manner, and by whom, (Cooper & Schindler, 2014).

Multistage qualitative communication study was used by Penton Media to determine the long-term feasibility of the reader service card that was being used for readers to be able to request addition information from a particular advertiser.

Although it saves costs, limiting the interview length by telephone is a disadvantage. Also when using face to face surveying instead of phone surveying, there is the ability to use visual or complex questions. Since it becomes easier for a participant to terminate a phone conversation,...
