The choice of which type of graph to use to represent data can strongly influence the ability of most people to get the correct information from it.
Graphs are used to make sense of the world around us.
In Science students are expected to translate information between graphical and numeric forms, Understand that y= mx + c represents a linear relationship, plot two variables from experimental or other data, determine the slope and intercept of a linear graph, draw and use the slope of a tangent to a curve as a measure of rate of change and understand the physical significance of area between a curve and the x-axis and measure it by counting squares as appropriate.
In Geography students will use graphs that show climate change, surface temperatures with trend lines or population prediction graphs and graphs showing a country’s relationship between income and life expectancy.
