Question

What three features should be present for a survey to be generalized to a larger population?
(1 point)
random selection of participants, at least 10 percent of the population surveyed, bias free questions
asking true/false questions, at least 10 percent of the population surveyed, random selection of participants
bias-free questions, less than 10 questions asked, at least 10 percent of the population surveyed
random selection of participants, unbiased questions, at least 50 percent of the population surveyed

Answer 1

random selection of participants, at least 10 percent of the population surveyed, bias free questions

(These ensure representativeness (random), no measurement bias (unbiased questions), and a sufficiently large sample to reduce sampling error.)
