‘Play as if you were at home’: dealing with biases and test validity
Guillaume Louvel · Oxford University Press eBooks · 2018
This chapter discusses the user testing process in a lab and the inevitability of biases when testing under these conditions. It also describes the difficulties to obtain the data needed by the researcher when the conditions are closer to real life, and the difficulties to project data to everyday situations when closer to experimental conditions. Lastly, it describes the importance of reducing biases in the study to increase its validity in order to obtain more useful and meaningful results.
