Our learning object is

Scatter plots: age and reaction time

  • Find out what a scatter plot is and how it can be used to investigate relationships between two variables. Analyse data for a pair of variables: a person's age and the time it takes them to react to a signal. Enter your personal data and plot it with other data on a graph. Use a line of best fit to identify if there is a positive or negative relationship between the two variables. This learning object is one in a series of five objects.

Statistics and Probability

- Data representation and interpretation
  • Use scatter plots to investigate and comment on relationships between two continuous variables.
  • Using authentic data to construct scatter plots, make comparisons and draw conclusions.

Key Learning Objectives:
  • Students explore the characteristics and uses of scatter plots.
  • Students use a scatter plot to identify if there is a positive or negative relationship between a pair of variables.
  • Students interpret bivariate data in tables and graphs.
