This dataset example introduces researchers to plotting a time series for a single variable. A time series plot is a particular kind of two-way scatter plot where time is plotted on the horizontal axis and values of the variable in question are plotted on the vertical axis. Such plots allow researchers to observe graphically any trends or patterns that might be present in a variable over time. This example uses a subset of data from the United States National Oceanic and Atmospheric Administration (NOAA) Climate at a Glance website. Understanding trends in global temperature will help researchers and policy makers better understand potential climate change and plan for its impact. The sample dataset used for this example has been cleaned and organized to make this example easier to follow. Interested readers should read the full documentation for the dataset before using it for research (https://www.ncdc.noaa.gov/cag/time-series/global).
