When you get a surprisingly low price on a product do you assume that you got a really good deal or that you bought a low-quality product? research indicates that you are more likely to associate low price and low quality if someone else makes the purchase rather than yourself (yan and sengupta, 2011). in a similar study n = 16, participants were asked to rate the quality of low-priced items under two scenarios: purchased by a friend or purchased yourself. the results produced a mean difference of mn = 2.6 and ss = 135, with self-purchases rated higher.
a) is the judged quality of objects significantly different for self-purchases than for purchases made by others? use a two-tailed test with \alpha = .05
b) compute cohen’s d to measure the size of the treatment effect
