Answer all questions in the spaces provided.
1 (a) (i) Rainfall variation in a location over a 12 year period is being investigated.A standard deviation calculation has been started in Figure 1.
Complete Figure 1 and then use the formula below Figure 1 to complete the standarddeviation calculation. Do all calculations to two decimal places.
