By weighting the competitions between 1 and 5, we have created an awards 'universe' in which the Grand Prix in a competition assigned the lowest possible weighting (10 Award Points multiplied by a Competition Weighting of 1) is equivalent to a Bronze in a competition with the highest possible weighting (2 Award Points multiplied by a Competition Weighting of 5). It also means that the minimum a campaign can win from a single competition is 2 points (2 Award Points multiplied by a Competition Weighting of 1), and the highest it can win is 50 points (10 Award Points multiplied by a Competition Weighting of 5).
First and foremost, a researcher must think very carefully about the population that will be included in the study and how to sample that population. Errors in sampling can often be avoided by good planning and careful consideration. However, in order to improve a sampling frame, a researcher can always seek more participants. The more participants a study has, the less likely the study is to suffer from sampling error. In the case of the response rate problem, the researcher can actively work on increasing the response rate, or can try to determine if there is in fact a difference between those who partake in the study and those who do not. The most important thing for a researcher to remember is to eliminate any and all variables that the researcher cannot control. While this is nearly impossible in field research, the closer a researcher comes to isolating the variable of interest, the better the results. (5)
