Data Sampling & Measurement
Understanding the representativeness of different subpopulations is complex when developing nationally representative surveys, but it is even more challenging when building samples from publicly shared user posts. MDI researchers work to understand how to reweight samples to make them more representative of populations of interest. They also develop standards for constructing different types of variables and determining the reliability of different types of measurements. This is particularly important when developing measurements using big data sources, e.g. social media, newspapers, mobile phones, satellite images, etc. Representative samples and reliable measurements are necessary for developing evidence-based public policy.
