Datasets usually provide raw data for analysis. This raw data often comes in spreadsheet form, but can be any collection of data, on which analysis can be performed.
These are the raw data as a .csv file used in the manuscript "Uplift gratuity: Effects of an Opportune Gift and its Timing on Tipping Behavior" by Frederic Hilkenmeier, Sascha Hoffmann, and Grzegorz Derkowski. The study analyzes the timing of a small gift offered by waiters on tipping behavior, showing that customers generously reciprocate a gift by significantly increasing gratuity. Closer temporal proximity between gift and payment even doubles this effect, indicating that servers can substantially - and effortlessly - raise their tips just by manipulating the saliency of the reciprocity norm. Statistical Analysis: ANCOVA IV: Experimental Condition DV: Gratuity_percentage Covariate: Billsize As described in the manuscript, we also provide a Reduced Dataset with only 54 subjects (dinner parties) per condition.
