This dataset is designed to teach how to plot a time series for a single variable and fit both a straight line and a non-linear curve to the data. The dataset is a subset of data derived from the United States Department of Agriculture (USDA) Database, and the example examines trends in barley yield per acre in bushels per year from 1876 to 2015. The dataset file is accompanied by a teaching guide, a student guide, and a how-to guide for SPSS.
