What is one true statment about EOCs?
The purpose of an EOC is to establish a central location to support incident response.
For what purpose multivariate analysis is used?
Used when you have an experiment with several related dependent measures. Also used to analyze data from a within subject design.
What is the purpose of mean absolute deviation?
Various answers to this question are possible.The mean absolute deviation (MAD) is a measure of the dispersion or spread of a sample or a population. So one of its purposes is as a measure.As such it's an alternative to the standard deviation that is said to be more robust in the sense that the sample MAD can be used to provide more accurate estimates of the population dispersion because it is less sensitive to outliers.Beyond this, some distributions that have no standard deviations do have MADs; for example, the Cauchy. This means that the dispersions of virtually all distributions can be compared in terms of their MADs.Please see the link.
What is best Interquartile range or Median absolute deviation?
The answer depends on the purpose. The interquartile range and the median absolute deviation are both measures of spread. The IQR is quick and easy to find whereas the MAD is not.
How do you convert wet measures to dry measures?
A pint is a pint is a pint in volume. However 16 oz in a pint is 16 oz in a pound only if it is water. A pint of flour does not weigh a pound as it is not as dense as water. A pint or 16 ounces dry measure of all-purpose flour weighs about 10 ounces (.625 of a pound) Chef Instructor Wayne Wilberding
What is the purpose of central tendency measures?
It is a measure of the middle or central value of a variable of interest. There are different measures of central tendency and their purposes are not exactly the same. However, the basic principle is that the observed values of the variable are more likely to be near the central tendency value than far from them. Some central tendency values cannot ever be observed. A normal number cube, for example, has a mean value of 3.5 but you cannot possibly throw a 3.5!

Does a tsunami have a purpose?
A tsunami is a reaction to an under water earthquake, land slide or a meteor that struck the earth. It's the dispersion of energy.

What is the purpose of quartile deviation?
In a data sample, the purpose of quartile deviation is a way to measure data dispersion instead of using the range. The quartile deviation is found by subtracting the lower quartile from the upper quartile, and dividing this result by two.
