Chapter 1: Q. 36 (page 52)

A question on a survey reads: "Do you prefer the delicious taste of Brand X or the taste of Brand Y?" Is this a fair question?

Short Answer

Expert verified

Introduction

Explanation

"Do you like the exquisite flavor of brand Xor the taste of brand Y?" the inquiry asks.
The interviewer expresses his preference for Brand Xby describing the flavor as "wonderful."
As a result, this is a skewed question.
