308 / 4 = 77
The median is 78.
92
Sum = 678 Count = 8 So Average = Sum/Count = 678/8 = 84.75
79 is the average
308 / 4 = 77
90 because its half with 88 and 92
It is 89.
When they ask for the 'mean' they are really asking for the average of all those numbers. All you have to do is add those up: 76+54+92+88+76+88+75+93+92+68+88+76+76+88+80+70+88+72= 1440 And then divide by how many numbers we added up. In this case, we added up 18 different numbers. So: 1440 / 18 = 80 80 is your 'mean' or average number.
88
76
The median is 78.
The mean of the data is 80.
92
Sum = 678 Count = 8 So Average = Sum/Count = 678/8 = 84.75
79 is the average
Sort the numbers into numerical order:54, 68, 70, 72, 75, 76, 76, 76, 80, 88, 88, 88, 88, 92, 92, 93The median is the middle number which as there are 16 numbers is the mean of the middle two (highlighted above):median = (76 + 80) ÷ 2 = 78.
