Data that can only take distinct values or is a category, e.g. shoe size, number of people.

Data that can be a value within a range, e.g. temperature, mass, height, etc.

Chart showing solid columns to present data; usually used when one variable is discrete.

A graph in which two continuous variables are plotted.  It is used to find if a relationship exists between the variables.

A line of best fit is drawn through a set of plotted points on a scatter graph, to best show the trend in the data displayed.

Science

In the Separation techniques unit, they will build on this knowledge to learn about separation techniques in terms of the particle model.

In the Y5 Properties, changes and separating materials unit, pupils learnt about mixtures, including solutions, and separation techniques including filtering and evaporation.
