The owner of a large catering service wants to collect feedback from her customers, so she designs a survey. She posts a link to the survey on her social media channels and asks her followers to respond. The survey asks questions about demographic information, food taste/preferences, and customer satisfaction. She receives 878 survey responses. The responses are kept anonymous. Which of the following is a problem with the survey? Select the best choice. Small sample size: not enough responses were submitted to be able to draw meaningful conclusions. Study type: a survey is not the best way to collect the information she is looking for. Honesty: there is a high probability that survey participants may have lied on this survey based on the questions that were asked. Randomization: survey participants were not randomly chosen, and self-selection may introduce bias or confounding in the responses
