The mean average of any one number is the number itself.
The mean average of 10, 14 and 18 is 14
It is: 21+18+15 = 54 and 54/3 = 18 which is the mean average
15.
mean average = sum of dataset / number of items in dataset = (14 + 18 + 13 + 15) / 4 = 60/4 = 15
As there is an even number of them, the median is the mean average of the middle two, namely (18+24)/2 = 21.
It is: 14+15+22+21 = 72/4 => 18 which is the mean average
The average is 18.
18 + 24 + 18 = 60/3 = 20 The average of the three numbers is therefore 20.
2 + 5 + 11 = 18 The mean is the same as the average, which is the sum of the numbers divided by the total number of numbers that were added, in this case three. So the mean is 18/3 = 6.
The average deviation from the mean, for any set of numbers, is always zero.The average deviation from the mean, for any set of numbers, is always zero.The average deviation from the mean, for any set of numbers, is always zero.The average deviation from the mean, for any set of numbers, is always zero.
The average of 18 and 22 is 18+22/2 = 20
The mathematical mean is another word for an average. To find the mean, add up all the numbers and divide the sum by how many numbers there were to begin with. In this case, when you add the numbers the sum is 137. Divide that by 9 and you get 15.2 as the average.
