3L completed their Stingrays fitness testing and graphed their group's vertical reach. We learned that there are two axes (pronounced "ax-ees") and Cormac pointed out that they are called the x-axis and the y-axis! Some of the columns are almost the same height because we jumped almost the same height.
Why does 3L think we need to use graphs?
"To show data in a way that is easy to understand and compare."
After learning about different measurements, it is important to label the axes with the correct units so we know what the numbers mean (150 centimetres? 150 litres? 150 kilometres?150 apples?)
