To find: The statement which is not a potential bias in the sampling method used in a study.
The survey must include call-in and online responses is the statement which is not a potential bias in the sampling method.Given:
To study the most popular tea brand consumed by Americans, a survey is conducted in a bust downtown location at lunchtime.
Explanation:Considering the sample which is not a true representation of the population and leads to biased results, Urban office employees are not representative of the general population is a potential bias.
The availability of the tea brands in the area of the survey may also impact the result to identify the most popular brand of tea, so it is also a potential bias.
The time of the survey also impacts the consumption of tea, so a lunchtime survey does not reflect people’s tastes at other times of the day is also a potential bias.
The survey to include the call-in and online responses does not matter as the brand of tea people ordering matters but the channel of the order does not matter, so it is not a potential bias to sampling method. So the correct answer is option d.
