Is the median closely related to variance and standard deviation?
No, it is not
Is it true that the standard deviation is equal to the square root of the variance?
Yes. Please see the related link, below.
Can standard deviation be a negative?
No. Standard deviation is the square root of a non-negative number (the variance) and as such has to be at least zero. Please see the related links for a definition of standard deviation and some examples.
Carefully define a standard normal distribution?
A mathematical definition of a standard normal distribution is given in the related link. A standard normal distribution is a normal distribution with a mean of 0 and a variance of 1.
What is a pattern closely related to?
A pattern closely related to is a recurring design or sequence of events that is connected or similar to another pattern. It can be a variation or extension of the original pattern, or it can share similarities in structure, shape, or behavior. Identifying closely related patterns can help in understanding underlying principles and making predictions or connections.
How do you calculate salary variance?
I believe you are interested in calculating the variance from a set of data related to salaries. Variance = square of the standard deviation, where: s= square root[sum (xi- mean)2/(n-1)] where mean of the set is the sum of all data divided by the number in the sample. X of i is a single data point (single salary). If instead of a sample of data, you have the entire population of size N, substitute N for n-1 in the above equation. You may find more information on the interpretation of variance, by searching wikipedia under variance and standard deviation. I note that an advantage of using the standard deviation rather than variance, is because the standard deviation will be in the same units as the mean.
Variance and standard deviation are one and the same thing?
No. But they are related. If a sample of size n is taken, a standard deviation can be calculated. This is usually denoted as "s" however some textbooks will use the symbol, sigma. The standard deviation of a sample is usually used to estimate the standard deviation of the population. In this case, we use n-1 in the denomimator of the equation. The variance of the sample is the square of the sample's standard deviation. In many textbooks it is denoted as s2. In denoting the standard deviation and variance of populations, the symbols sigma and sigma2 should be used. One last note. We use standard deviations in describing uncertainty as it's easier to understand. If our measurements are in days, then the standard deviation will also be in days. The variance will be in units of days2.
Is there a diet that works with blood type B?
There is no research which indicates a variance in food related to blood type. To lose weight you should follow a standard diet.
Is the volume variance a controllable variance from a spending point of view?
No, the volume variance is controllable but not related to spending. The volume variance calculates the dollar impact of producing more or less than the budgeted production volume. No, the volume variance is controllable but not related to spending. The volume variance calculates the dollar impact of producing more or less than the budgeted production volume.
