Google Consumer Surveys is a Do-It-Yourself research tool that allows the Do-It-Yourselfer to do anything he/she wants, including ruin the very project he/she is undertaking. In all of the following examples, the DIY researcher needed to specify a single-answer (“radio button”) question type, and in all of the following examples, the DIY researcher got it wrong, and specified a multiple-multiple-choice question type (“check all that apply”). This is no different than if a DIY homeowner went to Home Depot, bought materials, and put the roof on inside out, put the floor in upside down, and reversed the hot and cold water lines.
In every one of the following examples, the data from the Google Consumer Surveys project needs to be thrown away, and the questions needs to be re-asked.
And so on.
If you are a potential DIY researcher, and you are not sure whether to use a “radio button” question type, or a “check box” question type, go find a professional researcher to help you. You will come out way ahead in the long run.
