I am a big fan of cricket, i rate cricketers on the basis of their averages. Average is nothing but consistency.
Average is very simple but effective way of representing an entire group by a single value.
Average of any number of quantities will always be higher than the lowest value and lower than the highest value of items whose average is being taken.
1.Average = Sum of quantities/Number of quantities.
2.Suppose a man covers a certain distance at x kmph and an equal distance at y kmph,then the average speed during the whole journey is (2xy/x+y) kmph.
