As a research method, survey comes with an inherent truthiness that makes us inclined to believe surveys irrespective of their quality. This means people can find themselves basing important decisions on shonky research - so in the wrong circumstances, a poor survey can be more than just a waste of time and money, it can be dangerous.
Fortunately Caroline’s book is an easy-to-read, step-by-step guide to better surveys - from figuring out your research goals all the way through to results reporting.
My favourite parts of the book, though, are the little extras in there. Caroline provides a solid critique of some established gold standards - NPS, statistical significance, even Likert scales.
And I love the checklists and acceptance criteria, along with the pragmatic guides for survey improvement (sized for every time-budget). These really reduce the book down to its most actionable essence, and turn it from a book I’ve learned loads from into a reference book I’ll refer back to regularly.
A great investment for anyone without a quant research background.
