Sample 1; T Shirts
When I first read the article, I thought most people either just prefer to wear yellow, or it has a name brand tag as it is almost double the other shirt (shirt A). After learning about influencing factors, I now think it applies to the influence factor that is bias as, there are only two colours, blue and yellow. What if you do no the those colours? The other factor that applies to this sample is cost because some people, kids and adults, will purchase the product that is worth more, just to say that they have it. This may have even more of an effect as surrounded by peers in a school environment might make the students buy it so others see they got the more expensive one. In the future, when reading and interpreting survey data I will definitely take each influencing factors into account as sometimes you just fly through surveys to get them done, but actually taking time to break the questions down might end up being beneficial.
