9 15 15 15 16 (five data)
Range = 16 - 9 = 7
Mean = (9 + 15 + 15 + 15 + 16)/5 = 70/5 = 14
So we have:
(9 - 14)2 = (-5)2 = 25 (the square of the difference of data value and the mean value)
(15 - 14)2 = 12 = 1, 3(1) = 3
(16 - 14)2 = 22 = 4,
the sum is 32
The standard deviation = √(32/5) ≈ 2.5
B because the spread, in this case standard deviation, is larger.
It is 3.045
There are 16 trials.
Standard deviation is the square root of the mean. The mean for this set is (2 + 4 + 3 + 7)/4 = 16/4 = 4; the square root of this is 2.
What Five Numbers have a range of 5 a median of 16 and a mean of 15
3.898717738 is the standard deviation.
US IQ standard Deviation is 16.
B because the spread, in this case standard deviation, is larger.
It is 3.045
mean is 218 with a standard deviation of 16
19
16
It is 10.
There are 16 trials.
The mean absolute deviation is 2
Standard deviation is the square root of the mean. The mean for this set is (2 + 4 + 3 + 7)/4 = 16/4 = 4; the square root of this is 2.
an IQ of 132 in SD (standard deviation) of 16 and 130 in a SD of 15 , this mean top 2% of world's population according to the bell curve..for more info , search in google.
