The mean is the average value and the standard deviation is the variation from the mean value.
The mean deviation (also called the mean absolute deviation) is the mean of the absolute deviations of a set of data about the data's mean. The standard deviation sigma of a probability distribution is defined as the square root of the variance sigma^2,

The coefficient of variation is the ratio between the standard deviation and the mean.
No, since "between 3" doesn't mean anything. Do you mean between -3 and +3?
mean deviation =(4/5)quartile deviation
The mean is the average value and the standard deviation is the variation from the mean value.
Standard error of the mean (SEM) and standard deviation of the mean is the same thing. However, standard deviation is not the same as the SEM. To obtain SEM from the standard deviation, divide the standard deviation by the square root of the sample size.
If Larry gets a 70 on a physics test where the mean is 65 and the standard deviation is 5.8, where does he stand in relation to his classmates
Information is not sufficient to find mean deviation and standard deviation.
The mean deviation (also called the mean absolute deviation) is the mean of the absolute deviations of a set of data about the data's mean. The standard deviation sigma of a probability distribution is defined as the square root of the variance sigma^2,
Mean 0, standard deviation 1.
Mean = 0 Standard Deviation = 1
Mean and standard deviation are not related in any way.
Standard deviation can be greater than the mean.
Standard deviation is a measure of variation from the mean of a data set. 1 standard deviation from the mean (which is usually + and - from mean) contains 68% of the data.
No. A small standard deviation with a large mean will yield points further from the mean than a large standard deviation of a small mean. Standard deviation is best thought of as spread or dispersion.
