Diagrams and Graphs
Tables are a very simple way of storing information that we have gathered in a
neat way. However, there are often different ways for us to present or sort that
data so that it is easier to understand or find patterns We can use different types
of diagrams to help us group numbers. Two famous diagrams that are used for
this purpose are Carroll diagrams and Venn diagrams.
A Carroll diagram is a table with headings for each column and row describing
different numerical qualities. Every number in each column or row must have
| Example 1.|
A Venn diagram is made up of circles with each circle containing numbers with
a certain property. If a number has more than one of these properties, it will be
placed in the space where the circles overlap. If a number doesn’t have any of
the properties, it will be placed outside the circles.
We can use line graphs to illustrate how one quantity will affect how another
quantity changes. Measurements will be recorded as points on the graph and
then these points are joined together with lines.
