BIG Data Who & What

3,700 students purchase data for 32-weeks. Millions of data points collected. Millions of dollars spent.

WhereEvery on-campus point of sale for prepared food

WhenFall 2014 – Spring 2015

WhySet a baseline for current nutritional purchase (via

caloric intake, USDA food grouping, etc.)

Recruitment of Participants

450 students recruited Fall 2014 Pre-data collected (BMI, weight,

questionnaire = $25 incentive) Post-data (BMI, weight,

questionnaire = $25 incentive)

Page 14: Sxsw slidedeck

Recruitment of Participants

75 assigned to each group 75% engagement = $50 incentive

Engagement = follow and engage with assigned medium

Experimental Design & Group Assignment

Page 16: Sxsw slidedeck

12-week intervention 2 nutrition messages delivered per week

(specific to campus dining locations) To receive a $50 incentive participants must

respond to 75% of the messages:Instagram group must likeSnapChat group must view Slingshot group must SnapBack their most

recent mealFacebook group must likeFace-to-face group must attend in personControl group – no enrollment or action

Available from 12-2: $4.99 at the Union

Social media purposefully chosen for this study for graduated levels

of engagementFacebook = Baseline (many nutrition educators and dining facilities use it)

Instagram = passive (only have to “like”)

SnapChat = moderate engagement (must watch before it dissappears FOREVER)

SlingBox = high engagement (must sling-back photo so see our message)

Face-to-face = traditional education medium

Control = gotta have it for strong research design ;-)
