The main issue with this sampling method is that it is likely to produce a biased sample. By only surveying gym members at a specific location (a gym), the company is only capturing the preferences of individuals who are physically active and likely to be health-conscious. This group may not represent the wider population, including people who do not frequent gyms and may have different preferences regarding sports drinks. Therefore, the results of the survey may not be generalizable to the overall market, leading to potentially misleading conclusions about the sports drink's popularity among all consumers. A more representative sampling method would involve surveying a broader range of individuals from various demographics and locations.
