What Conditions necessary for a measure of variation to have a positive value?
It is that the measure is somehow related to the absolute value of the observations compared to some fixed value and also that there IS some variation.
Which measure of dispersion represents variation from the mean?
Are you talking of this in means of Statistics? If you are, then the variation from the mean is measured in standard deviation.
What are the criteria for choosing measure of central tendency and measure of variation?
Central tendency is measured by using the mean, median and mode of a set of numbers. Variation is measured by using the range, variance and standard deviation of a set of numbers.
What is the importance of coefficient of variation?
It's a way of obtaining a measure of dispersion that is dimension-free.
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.
What Conditions necessary for a measure of variation to have a positive value?
It is that the measure is somehow related to the absolute value of the observations compared to some fixed value and also that there IS some variation.
Why do we need the standard deviation?
The standard deviation is a measure of the spread of data.
What does the Beaufort scale measure why is it necessary?
The Beaufort scale is a measure that relates wind speed to observed conditions. The intention is to be practically useful to mariners.
Coefficient of variation is a measure of relative variation. True or False?
True
Does variation mean range in math terms?
No. A range is one measure of variation. It is easy to find, but it is also a rather crude measure.
What is measure of variation?
A measure of variation, also called a measure of dispersion, is a type of measurement that details how a set of data is scattered from a central or neutral point of origin. Range, variance and standard deviation are three measures of variation that are commonly used.
Describe the impact of proposition 13 on country funding?
"Prop 13" would be a local measure and more information would be necessary to respond.
Which measure of dispersion represents variation from the mean?
Are you talking of this in means of Statistics? If you are, then the variation from the mean is measured in standard deviation.
What is an advantage of using the range as a measure of variation?
It is simple to calculate.
What is the Measure of the degree of variation among a set of events?
scatterplot
Write an original definition for genetic variation?
The genetic variation of a population is a measure of how much individuals in a population differ genetically.
Which measure of variation is appropriate when using the mean?
The variance or standard deviation.
