Description: The following table shows the numbers of cell phone subscriptions (in thousands) in the United States for various years. Construct a time-series graph of the data. "Linear" growth would result in a graph that is approximately a straight line. Does the time-series graph appear to show linear growth? (TABLE CAN'T COPY)

Key Concepts

Time Series Data

This concept involves data points collected or recorded at successive points in time, often at uniform intervals. In the context of the question, it refers to the cell phone subscription numbers measured over several years, allowing for the analysis of trends and patterns as they evolve over time.

Data Visualization

Data visualization entails the graphic representation of data in charts or graphs, which makes it easier to identify trends, patterns, and outliers. For time-series data, a properly constructed graph helps to visually assess how the data changes over time, such as identifying whether the growth appears linear or follows another trend.

Linear Growth

Linear growth describes a situation where the data increases (or decreases) by a constant amount over evenly spaced time intervals. When graphed on a time series, linear growth is characterized by data points that approximately form a straight line, indicating a constant rate of change.
