BU288 Lecture Notes - Lecture 2: Electronic Body Music, Participant Observation, Dependent And Independent Variables
Document Summary
Arguments for tip increase; social pressure, no discussion, faster/easier. Arguments for tip decrease; you pay tip & total amount all together - less pressure to add tip, with pre set options on devices people may click lowest option, people that don"t like technology (annoyance) Further analyzing what factors may effect whether the tip increases or decreases; type of restaurant/bar, age of clientele, menu prices. Independent variable; whether or not we"re using hand held device. Mediator (variable that explains a relationship); social pressure, convenience, discussion etc. Moderator (variables that change a relationship); perception of device, restaurant clientele, set menu prices etc. Hypothesis; h1 = tips will go up using devices, h2= tips will go down using devices. Strengths & weaknesses; strengths - clear research question, clear hypothesis, objective dv & iv, weaknesses - correlational design; not an experiment (can"t establish causality), no way to know if mediators and moderators are okay.
