Example of Time Series Plot

A marketing analyst wants to assess trends in tennis racquet sales. The analyst collects sales data from the previous five years to predict the sales of the product for the next 3 months. As part of the initial investigation, the analyst creates a time series plot to see how sales have changed over time.

  1. Open the sample data, TennisRacquetSales.MTW.
  2. Choose one of the following:
    Mac
    • Graphs > Time Series Plot > Single Y Variable: Simple
    • Statistics > Time Series > Time Series Plot > Single Y Variable: Simple
    PC
    • Graphs > Time Series Plot > Single Y Variable: Simple
    • Statistics > Graphs and Calculations > Time Series Plot: Single Y Variable
  3. In Y variable, enter Racquets.
  4. Click OK.

Interpret the results

The time series plot shows a clear upward trend. There may also be a slight curve in the data; the increase in the data values seems to accelerate over time.
