The data record daily measurements of edible plate waste collected during lunchtime across treatment and control dining halls over a four-week experimental period in October–November 2024. Key variables include the total weight of food waste collected, the number of plates sampled, average waste per plate, treatment assignment, collection time, and weekday indicators. The associated research manuscript is currently under review.The field experiment was planned for 20 weekdays across two dining facilities (40 observations). Due to scheduling constraints and assistant availability on three days, three observations were not collected. The final dataset therefore contains 37 observations.<a href="http://creativecommons.org/publicdomain/zero/1.0">CC0 1.0</a>original_data-1.tab407text/tab-separated-valuesUNF:6:mS2g47BR7tfS3IYzjF+9Pg==Raw dataset in Stata dataset format. original_data.tab407text/tab-separated-valuesUNF:6:mS2g47BR7tfS3IYzjF+9Pg==Raw dataset used in the empirical analysis.Treated_data.tab3714text/tab-separated-valuesUNF:6:rwfOGquvlv+w6PRvjPWQDg==Stata dataset after the treatments on the original dataset.0.040.00.750.43852900965351461.00.0.1.0UNF:6:JNDn8sfhtXXePWdBCOUvEw==7.960000038146973.37.014.03.5499999523162848.3554054015391593.02.2517173918036417UNF:6:HVlnPuA+6VLSOop20rI2oQ==100.03.0101.37837837837837100.037.0.2.822049603384739112.0UNF:6:LTIXW7l//T4bNpv8h6+/aA==.127.269996643066482.0854052981814835.537.079.599998474121120.3274422519881453.0UNF:6:12JDn1N2pLXUzi+fNrkaBQ==0.0.1.00.50.50.00.506369683541833340.0UNF:6:mK/LEJ8X3R0tm5w3vCbSEg==UNF:6:3YWYOelqmr0x5FWuDt09Mg==40.030.08.3946393591368753.0.8.026.59459459459459337.0UNF:6:FbJGSOMvUFyn+wO7dDTk0A==week0.43852900965351460.01.040.01.00.0.0.75UNF:6:JNDn8sfhtXXePWdBCOUvEw==totalweight14.03.08.3554054054054053.55.37.02.25171736261038777.96UNF:6:HVlnPuA+6VLSOop20rI2oQ==numplate.2.822049603384739100.03.037.0112.0100.0101.37837837837837UNF:6:LTIXW7l//T4bNpv8h6+/aA==averageweight20.3274423504637453.082.08540532432433127.27.35.579.59999837.0UNF:6:12JDn1N2pLXUzi+fNrkaBQ==interv0.50.51.0.0.00.040.00.5063696835418333UNF:6:mK/LEJ8X3R0tm5w3vCbSEg==dateUNF:6:3YWYOelqmr0x5FWuDt09Mg==coltime.30.08.040.08.39463935913687537.03.026.594594594594593UNF:6:FbJGSOMvUFyn+wO7dDTk0A==Post intervention indicator, week = 0: before treatment; week = 1: after treatme1.01.00.00.00.4349588362008399.37.00.7567567567567567UNF:6:vSOx7yUApIK54j9Feg2CcQ==Total weight of edible food waste collected each day (kg).2.25171739180364178.35540540153915914.03.549999952316284.7.9600000381469730.037.0UNF:6:6jDVVocoWq8+5MISC8ko2Q==Number of plates collected0.0100.0112.0100.0101.37837837837837.37.02.822049603384739UNF:6:2uu6PK3SMjpiGGOE/hltfg==Average weight of food waste per plate (grams), calculated as totalweight / nump35.579.599998474121120.32744225198814582.085405298181480.037.0.127.2699966430664UNF:6:GdoAFslCPQGcFX+HBN+yEg==Treatment indicator for experimental group assignment, Interv = 0: control group0.5135135135135136.0.00.00.50671170970953161.01.037.0UNF:6:WBTxe5Da3Pp7qDByULwicQ==Calendar date of the experimental period.UNF:6:R3BGu9AKYu8kIMabFytSKQ==Time required to collect the sampled food waste plates (minutes).40.00.030.037.0.8.3946393591368758.026.594594594594593UNF:6:lg85eFjcFCfx3FLttkBc3g==Treatment × Week interaction1.00.0.37.00.491672392698371650.00.378378378378378450.0UNF:6:nfHl0+F4IMGpZ5+O4dsKdQ==UNF:6:R3BGu9AKYu8kIMabFytSKQ==Weekday indicator, weekday = 1: Monday … weekday = 5: Friday, weekday = 6: Satur6.0.3.03.0810810810810810.037.01.01.4216261889192325UNF:6:90rP3C5cA3vB8bXvJ+AWqw==Week of experiment (1–4)1.12105162983546712.4864864864864870.04.01.0.2.037.0UNF:6:QuO37dBdm7/6oxGh5T+/Hg==esample() from estimates store1.037.01.00.01.01.0.0.0UNF:6:IaRvGG+smR6F2MFJike4tA==esample() from estimates store0.0.1.037.00.01.01.01.0UNF:6:IaRvGG+smR6F2MFJike4tA==esample() from estimates store.0.01.01.00.01.01.037.0UNF:6:IaRvGG+smR6F2MFJike4tA==field_experiment_analysis.doStata code used to replicate the statistical analysis in the paper. text/x-stata-syntaxREADME.txtInstructions for using the attached datasets and the Stata code.text/plain
