The data is plotted on a pair of axes as coordinates. Scatter graphs can be used to comment about correlation, the relationship between the two variables. A line of best fit can be drawn through the data and used to help estimate a missing value. For example, Here is a scatter graph ...
Here, the red line is a line of best fit for the population data, and the blue arrow indicates an upward trend. You may have to draw a line of best fit to represent the correlation of the data. Step-by-step guide: Line of best fit (coming soon) There are limitations to this that...
It’s time to end the myth of the ‘maths geek’ 8 key trends in this year’s A-level results “That is going to be tough, and will require some very sophisticated redesign of curricula,” adds Brewin. And even then, this won’t solve the debate over whether maths is best don...
