respondents who are preferably the primary purchaser in their household and have some knowledge regarding EF products. The more accurately we are able to have our sample represent this population, the more accurate our final results will be.

obtain, as participants may easily be accessible and available (Frankfort-Nachmias & Nachmias, 2008). However, it may skew the sample, tainting it through introducing sampling bias. As a result, this strategy may not culminate in a representative sample of the population (Frankfort-Nachmias & Nachmias, 2008). Likewise, purposive sampling has the drawback of being based on the subjective judgment of a researcher to obtain a sample (Frankfort-Nachmias & Nachmias, 2008). Since it is impossible to…

are sample availability, accessibility, requires little time and effort, and cost effectiveness for the researchers, thus, the word convenience. However, sampling method suffers from a major disadvantage that relates to inaccurate representation of the population, which can distort results (Wisegeek, n.d.).

Another type of sampling is systematic random sampling (Chamberlain, 2016). Using this method, researchers should develop a comprehensive list that is not structured (Chamberlain, 2016). Once the list has been compiled, the researcher should choose a random spot on that list, based off of the total sample size, and then select by interval moving forward (Chamberlain, 2016). While drawing a random sample is ideal, it is not always feasible. Therefore, another alternative sampling approach,…

Measuring validity is important because it determines the impact of research. Validity is defined as “an integrated, evaluative judgment of the degree to which empirical evidence and theoretical rationales support the adequacy and appropriateness of inferences and actions based on test scores or other modes of assessment” (Salkind, 2010, p.1). There are many criteria of rigorous research, for example, internal validity, external validity, objectivity of observer, replicability, and reliability…
