Yes - but the distribution is not a normal distribution - this can happen with a distribution that has a very long tail.

Can standard deviation be greater than mean?

Standard deviation can be greater than the mean.


What does it indicate if the mean is greater than the standard deviation?

It does not indicate anything if the mean is greater than the standard deviation.


Can the mean be less than the standard deviation?

In general, a mean can be greater or less than the standard deviation.


How do you calculate mean and Median smaller then Standard deviation?

In the same way that you calculate mean and median that are greater than the standard deviation!


Is the mean for a set of data always greater than the standard deviation?

Yes; the standard deviation is the square root of the mean, so it will always be larger.


Is mean deviation less than standard deviation?

Yes, the mean deviation is typically less than or equal to the standard deviation for a given dataset. The mean deviation measures the average absolute deviations from the mean, while the standard deviation takes into account the squared deviations, which can amplify the effect of outliers. Consequently, the standard deviation is usually greater than or equal to the mean deviation, but they can be equal in certain cases, such as when all data points are identical.


What are all the values a standard deviation can take?

The standard deviation must be greater than or equal to zero.


Why is the standard error a smaller numerical value compared to the standard deviation?

Let sigma = standard deviation. Standard error (of the sample mean) = sigma / square root of (n), where n is the sample size. Since you are dividing the standard deviation by a positive number greater than 1, the standard error is always smaller than the standard deviation.


What is the difference between a general normal curve and a standard normal curve?

A standard normal distribution has a mean of zero and a standard deviation of 1. A normal distribution can have any real number as a mean and the standard deviation must be greater than zero.


Can coefficient of variation be greater than 100?

Yes, the coefficient of variation (CV) can be greater than 100%. The CV is calculated as the ratio of the standard deviation to the mean, expressed as a percentage. If the standard deviation is greater than the mean, which can occur in certain datasets, the CV will exceed 100%, indicating high relative variability compared to the average value.


Is the standard deviation best thought of as the distance from the mean?

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.


What is the z score of 1.0?

It is the value that is one standard deviation greater than the mean of a Normal (Gaussian) distribution.
