Where the exponential pdf is f(x) = L*exp(-Lx), the standard deviation is 1/L and is the same as the mean of the distribution. See related link.

What are the assumptions of standard deviation?
The standard deviation is the standard deviation! Its calculation requires no assumption.
What is the difference between standard error of mean and standard deviation of means?
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.
Difference Standard Deviation of a portfolio?
difference standard deviation of portfolio
What is the square of the standard deviation called?
The square of the standard deviation is called the variance. That is because the standard deviation is defined as the square root of the variance.
A standard normal distribution has a mean of and standard deviation of?
Mean 0, standard deviation 1.
How do you calculate sample standard deviation?
Here's how you do it in Excel: use the function =STDEV(<range with data>). That function calculates standard deviation for a sample.
How do you do standard deviation on Microsoft Excel?
Use the STDEV() function.
A function takes the exponential function's output and returns the exponential function's input?
A __________ function takes the exponential function's output and returns the exponential function's input.
What is a frequency distribution defined by its average and standard deviation?
The triangular, uniform, binomial, Poisson, geometric, exponential and Gaussian distributions are some that can be so defined. In fact, the Poisson and exponential need only the mean.
What are the assumptions of standard deviation?
The standard deviation is the standard deviation! Its calculation requires no assumption.
Is probability density function and gaussian distribution function are same?
yes, h=1/sigma(standard deviation)
What does the sample standard deviation best estimate?
The standard deviation of the population. the standard deviation of the population.
What is the parent function for the exponential function?
The parent function of the exponential function is ax
What is standard deviation of 155.45?
The standard deviation is 0.
If quartile deviation is 24. find mean deviation and standard deviation?
Information is not sufficient to find mean deviation and standard deviation.
Is the inverse of an exponential function the quadratic function?
No. The inverse of an exponential function is a logarithmic function.
What is the relationship between standard deviation and variance?
Standard deviation is the square root of the variance.
