Our learning object is

Scatter plots: age and reaction time []

Description
 * 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.

 * What the learner will do:** ||< **Declarative Knowledge**
 * What the learner will know:** ||
 * < # Identify and create scatter plots.
 * 1) Interpret authentic data to draw conclusions.
 * 2) Analyse data and recognise patterns and relationships. ||< # Key terms e.g. scatter plot, scatter diagram, line of best fit, trend line, positive/negative relationship/correlation/association, axes, graph, bivariate data, variables, horizontal and vertical axis, cluster.
 * 3) Appropriate use of graphs and how to apply this learning.
