The mean is 8 because: (1+6+10+11+12)/5=8 We know that the Arithmetic Mean of a data set = (sum of all the items)/ number of items. =(1+6+10+11+12)/5 =(40)/5 =8. The Arithmetic Mean of 1, 6, 10, 11, and 12 is 8.
5+7+9+12+12 = 45 and 45/5 = 9 which is the mean average
One meaning could be "Arithmetic Mean". Thus is you have a sample set containing number say 1, 4, 5, 2, 7, 9, 21, 12, then the Arithmetic mean would be the sum of the numbers divided by the number of numbers. In this case it would be (1 + 4 + 5 + 2 + 7 + 9+ 21 + 12)/8 = 61/8 = 7 and 5/8
26 47 + 5 / 2
The average mean is: (11+12+13+14+15)/5 = 13
