Constructing time series graphs

Graphical representations of data: scatter graphs and time series

Unit Summary

In this unit pupils will learn how to interpret and extract data from scatter graphs and time series graphs.

Lesson Summary

You will learn to construct time series graphs.

Key Notes

  • Time series graphs are a visual representation
  • Time series graphs plot frequency over time
  • Consecutive points are joined by straight line segments

Vocabulary To Learn

  • Time series graph: Time series graphs show data over a time period. The time period is always shown on the x-axis. Data points are joined chronologically by line segments.

Common Mistakes To Avoid

  • Time series graphs always use years as the time interval.

3 Quick Questions (With Answers)

1. Solve this in steps: explain the method from this lesson and why each step matters.

Time series graphs are a visual representation. Time series graphs plot frequency over time.

2. Use this key word in a maths sentence and explain it clearly. 'Time series graph'

Time series graphs show data over a time period. The time period is always shown on the x-axis. Data points are joined chronologically by line segments. Use this word when showing your method, then check your final answer is reasonable.

3. Spot and fix this common maths mistake.

Mistake: Time series graphs always use years as the time interval. Correction: The time interval used in a time series graph depends on what the graph is intended to show.
