What is the pattern of a variability within a data set called?
The range, inter-quartile range (IQR), mean absolute deviation [from the mean], variance and standard deviation are some of the many measures of variability.
What does the standard deviation of a set of data tell you?
It tells you how much variability there is in the data. A small standard deviation (SD) shows that the data are all very close to the mean whereas a large SD indicates a lot of variability around the mean. Of course, the variability, as measured by the SD, can be reduced simply by using a larger measurement scale!
What does Lack variability mean?
Lack - verb, does not haveVariability - noun, the quality of change or difference
Why are the measures of dispersion necessary to describe a set of data?
Sets of data have many characteristics. The central location (mean, median) is one measure. But you can have different data sets with the same mean. So a measure of dispersion is used to determine whether there is a little or a lot of variability within the set. Sometimes it is necessary to look at higher order measures like the skewness, kurtosis.
How many standard normal distributions are there?
Only one. A normal, or Gaussian distribution is completely defined by its mean and variance. The standard normal has mean = 0 and variance = 1. There is no other parameter, so no other source of variability.
Does the coefficient of variation measure variability in a data set relative to the size of the arithmetic mean?
Yes.
What measures are used to describe variability?
Generally, the standard deviation (represented by sigma, an O with a line at the top) would be used to measure variability. The standard deviation represents the average distance of data from the mean. Another measure is variance, which is the standard deviation squared. Lastly, you might use the interquartile range, which is often the range of the middle 50% of the data.

What does rainfall variability mean?
rainfall variabilty
What is the most commonly used measure of variability?
Standard deviation is a commonly used measure of the variability of a set of measurements.But that usually refers to a 'normal' distribution - an assumption that the results are distributed according to a 'normal' (Gaussian) curve. There are several other types of distribution, Poisson, Bernoulli, and others.It is important to note that the application of standard deviation becomes less and less useful as one approaches the extremes of the set of measurements.
What does variability mean in math?
Variability is an indicationof how widely spread or closely clustered the data valuesnare. Range, minimum and maximum values, and clusters in the distribution give some indication of variability.
Does variability include mean median mode and range?
No, it does not
What is the conjunction of will not?
There is no conjunction of will not.Maybe you mean contraction.If you do then won't is the contraction
What is variability in math terms?
range,mode ,mean and cluster
What art of speech is the word or?
Assuming you mean PART of speech (not ART), "or" is a conjunction.
What does the standard deviation of a set of data tell you?
