A Note on A Catalog of Biases in Questionnaires [Response to Letter]
Abstract
We would like to thank Dr Harrow (1) for pointing out a flawed example in our paper (2). As he notes, the recommended question should be: How many cigarettes do you smoke per day? [ ] None [ ] 14 [ ] 524 [ ] 25 or more The previously recommended category 4 or less was a typographical error.
