You will need to write over some of the slides. Useful phrases to interpret a graph. A conversion graph is used to change one unit into another. In real-life contexts, the intercept, gradient and area underneath the graph can have important meanings such as a fixed charge, speed or distance. Knowing which factors do and don't vary together improves forecasting accuracy. Created: Nov 1, 2011| Updated: Dec 11, 2014. Each observation (or point) in a scatterplot has two coordinates; the first corresponds to the first piece of data in the pair (thats the X coordinate; the amount that you go left or right). registered in England (Company No 02017289) with its registered office at 26 Red Lion Probability 4 - Experimental Probability (Relative Frequency), Probabilities from a table - increasingly difficult. Many times executives assume that measures vary together when they do not or do not vary in concert with one another when they do.

The data on the sheet has come from somewhere else but I’m not sure exactly where! The matching activity provides a great opportunity to discuss the fact that correlation does not equal causation. (You don’t even need the scatter graph to see that this point is the outlier as it is quite clear in the table too; the student achieved the best result of the group with barely any revision.) Know that correlation does not mean causation. Conditions. Also the person trying to understand the story, needs some basic knowledge about graphs. London WC1R 4HQ.
