The answer depends on the individual measurement in question as well as the mean and standard deviation of the data set.
Z-Score tells how many standard deviations a measurement is away from the mean.
the Z score, or standard score.
Standard deviation is a measure of the spread of data around the mean. The standardized value or z-score, tells how many standard deviations the measurement is away from the mean, and in which direction.z score = (observation - mean) / standard deviationStandard deviation is the unit measurement. This tells what the value a decimal is.
95 percent of measurements are less than 2 standard deviations away from the mean, assuming a normal distribution.
How many standard deviations is 16.50 from the mean?
The "z-score" is derived by subtracting the population mean from the measurement and dividing by the population standard deviation. It measures how many standard deviations the measurement is above or below the mean. If the population mean and standard deviation are unknown the "t-distribution" can be used instead using the sample mean and sample deviation.
That depends on what the standard deviation is.
You cannot have a standard deviation for 1 number.
It is 1.28
z-score or standard score... tells you how many standard deviations away from the mean a particular number is in relations to all numbers in a population (or sample)
There are 8 pints in a gallon in 'standard liquid measurement'.
16.5 is 1 standard deviation from the mean. If you add the mean of 14 to the 1 standard deviation of 2.5, the result is 16.5.
Approximately 2 standard deviations (1.96, actually) from the mean. That is important to know that if one has a sample of 1000 values, if one selects a threshold at +/- 2 standard deviations from the mean, then one expects to see about 25 values exceeding those thresholds (on each side of the mean)
It depends on the shape of the distribution. For standard normal distribution, a two tailed range would be from -1.15 sd to + 1.15 sd.
4,000,000 pounds are equal to 2000 short tons, which is the US accepted measurement. For the International Standard equivalent, the answer is 1,814.36 tonnes. The International Standard measurement is based off of the kilogram, where as the US Standard measurement is based off of the pound.
in US measurement 6 yards=17.999964 in standard measurement 6 yards= 18 feet
