US IQ Standard deviation?
US IQ standard Deviation is 16.
What is the standard deviation for 11 13 15 16 20 21?
3.898717738 is the standard deviation.
Mean 266 and standard deviation is 16 what percentage of human pregnancies last between 250 and 282?
If G is a random variable representing the gestation period, an it is assumed to have a normal distribution with the given mean and standard deviation, then Prob(250 < G < 282) = Prob(-1 < Z < 1) where Z has the standard normal distribution. = 0.6827 = 68.3%
What percentage of people have IQ's at 118?
How can I find out what is considered a 'good' IQ? I got a score of 118 and am wondering if that is normal or slightly above? Can anyone answer? Please email me directly: abigail.f.miller@gmail.com.Thank you in advance and I appreciate the help.Sincerely,AbigailIQ is a statistic based on standard deviation, that is how far the subject is from the baseline (or average). Each standard deviation is granted 12 or 16 points depending on the test. A single standard deviation is 68.2% of the popuation, meaning 68.2% of people have within 12-16 IQ points of 100. 100 being the baseline average.Assuming half fall above average and half fall below, this means that only 15.9% of the population has above a 112 or 116 IQ depending on the actual test scaling. So, in either case you are in the top 15.9% in regards to raw IQ.
Scores on the sat exam approximate a normal distribution with µ equals 500 and sd equals 100 use this distribution to determine the percentage of sat scores that fall above 600?
The answer is about 16% Using the z-score formula(z = (x-u)/sd) the z score is 1. This means that we want the percentage above 1 standard deviation. We know from the 68-95-99.7 rule that 68 percent of all the data fall between -1 and 1 standard deviation so there must be about 16% that falls above 1 standard deviation.

What is the standard deviation for 11 13 15 16 20 21?
3.898717738 is the standard deviation.
What is the Calculated Standard Deviation In The Following Data 13 12 9 15 11 16 17 8 12 7 12?
It is 3.045
The mean of A is 14 with a standard deviation of 4.2. The mean of B is 16 with a standard deviation of 4.4 Which is more dispersed?
B because the spread, in this case standard deviation, is larger.
If a normal distribution has a mean of 16 and standard deviation 3 then?
19
Average usmle score?
mean is 218 with a standard deviation of 16
If the variance of the data a population is 256 what is the standard deviation of the data values?
16
What is the mean absolute deviation for 12 9 12 13 15 8 11 14 10 and 16?
The mean absolute deviation is 2
What is the number of trials in a binomial distribution that has a mean of 8 and a standard deviation of 2?
There are 16 trials.
What is the standard deviation of these four scores 2 4 3 7?
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 is the average length of a business cycle?
average length from trough to trough of 46 months and standard deviation of 16 months.
What is the range and standard deviation of 9 15 15 15 16?
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
