What is percentile deviation?
A standard deviation in statistics is the amount at which a large number of given values in a set might deviate from the average. A percentile deviation represents this deviation as a percentage of the range.
A score of 0.60 standard deviation represents what score of percentile?
It depends on the underlying distribution. If Gaussian (standrad normal) then the percentile is 77.
What percentile does a score of 351.5 on MAT equate to?
The Miller Analogies Test scores have a mean of 400 and a standard deviation of 25, and are approximately normally distributed.z = ( 351.5 - 400 ) / 25 = -1.94That's about the 2.6 percentile.(Used wolframalpha.com with input Pr [x < -1.94] with x normally distributed with mean 0 and standard deviation 1.)
Is sigma the same thing as standard deviation?
The lower case sigma character (σ) represents standard deviation.
What percentile rank would you be in if you scored a 720 on the GRE when the mean equals 500 and the standard deviation equals 100?
You would be in the 99th percentile (98.61, to be more precise).

What is the standard deviation of height in the US population?
The standard deviation of height in the US population is approximately 3 inches.

You would be in the 99th percentile (98.61, to be more precise).
How much is 84 percentile equals mean plus 1 standard deviation or mean plus 1.4 standard deviation. Can you give me reference also please?
The cumulative probability up to the mean plus 1 standard deviation for a Normal distribution - not any distribution - is 84%. The reference is any table (or on-line version) of z-scores for the standard normal distribution.
What do you get with mean minus std dev?
When you subtract the standard deviation from the mean, you get a value that represents one standard deviation below the average of a dataset. This can be useful for identifying lower thresholds in data analysis, such as determining the cutoff point for values that are considered below average. In a normal distribution, approximately 68% of the data falls within one standard deviation of the mean, so this value can help in understanding the spread of the data.
What refund amount represents the thirty-fifth percentile of tax returns when given an average income of 3036 and a standard deviation of 950?
Assuming a normal distribution of incomes: 2672z = ( 2672 - 3036 ) / 950 = -0.383157895Pr{z
What are the assumptions of standard deviation?
The standard deviation is the standard deviation! Its calculation requires no assumption.
What does the sample standard deviation best estimate?
The standard deviation of the population. the standard deviation of the population.
How do you calculate plus or minus one standard deviation?
To calculate plus or minus one standard deviation from a mean, first determine the mean (average) of your data set. Then calculate the standard deviation, which measures the dispersion of the data points around the mean. Once you have both values, you can find the range by adding and subtracting the standard deviation from the mean: the lower limit is the mean minus one standard deviation, and the upper limit is the mean plus one standard deviation. This range contains approximately 68% of the data in a normal distribution.
