Question

decide whether the following statement makes sense (or is clearly true) or does not make sense (or is clearly false). explain your reasoning. the tv survey got more than 1 million phone - in responses, so it is clearly more valid than the survey by the professional pollsters, based on interviews with only a few hundred people. choose the correct answer below. a. the statement does not make sense. the eight guidelines for evaluating a statistical study need to be reviewed before one study can be called more valid than another. b. the statement makes sense. when conducting a survey, more responses will make it more valid than another survey with fewer responses. c. the statement does not make sense. when collecting data for a survey, phone - in responses are more valid than interviews. d. the statement makes sense. when a survey has over 1 million responses, the large sample size gets rid of any bias.

Explanation:

A large sample size does not automatically mean a survey is free of bias. Phone - in responses are often self - selected and can introduce bias. Also, the validity of a survey depends on many factors like sampling method, question design etc., not just the number of responses. Just because a survey has more responses does not necessarily make it more valid than one with fewer responses. And all statistical studies should be reviewed regardless of the number of responses.
