Title

Time Series Analysis of DMV Survey Response Rates

Presenter

Casey Schafer

Abstract

Last summer I worked at the Survey Research Center at Oregon State University, where I used the statistical techniques of linear modeling and time series to analyze the response rates of DMV surveys from 1994 to 2015. Findings indicate that response rates have dropped significantly and thus the results of the surveys may be affected by non-response bias. I present the methods for determining the linear model, graphical examinations of the data, conclusions of the study and their implications affecting the DMV and all surveyors.
