What else can I help you with?
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 the coefficient of variation?
The coefficient of variation is the ratio between the standard deviation and the mean.
What is a disadvantage of using the range as a measure of variation?
One disadvantage of using the range as a measure of variation is that it only considers the highest and lowest values in a dataset, ignoring the distribution of the other values in between. This can lead to a misleading representation of variability, especially in datasets with outliers or extreme values that can skew the range. Additionally, the range does not provide any information about how data points cluster around the mean or median, making it less informative than other measures like the interquartile range or standard deviation.
What is the best measure of center and measure of variation (spread) to use with a data set that has an outlier?
When a data set has an outlier, the best measure of center to use is the median, as it is less affected by extreme values compared to the mean. For measure of variation (spread), the interquartile range (IQR) is preferable, since it focuses on the middle 50% of the data and is also resistant to outliers. Together, these measures provide a more accurate representation of the data's central tendency and variability.
What is difference between absolute measure of dispersion and relative measures of dispersion?
The Absolute Measure of dispersion is basically the measure of variation from the mean such as standard deviation. On the other hand the relative measure of dispersion is basically the position of a certain variable with reference to or as compared with the other variables. Such as the percentiles or the z-score.
Which measure of variation is appropriate when using the mean and which is appropriate when using the median?
When using the mean: the variance or standard deviation. When using the median: the range or inter-quartile range.
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.
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.
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.
Does the coefficient of variation measure variability in a data set relative to the size of the arithmetic mean?
Yes.
What is the appropriate measure of central tendency when evaluating the age of a group?
mean
What are the advantages and disadvantages of coefficient of variation?
One the main advantage of using the coefficient of variation over the standard deviation to measure volatility is the fact that CV is normalized and can be used to directly compare different asset's volatility. The standard deviation must be used in the context of the mean of the data.
How do you measure forse?
If you mean force (not forse) then you measure it using newtons.
What does one standard deviation mean?
Standard deviation is a measure of variation from the mean of a data set. 1 standard deviation from the mean (which is usually + and - from mean) contains 68% of the data.
What unit measure is to measure the length of a computer cable?
Not sure what cable exactly you mean, but the meter is quite appropriate to measure cables in general.
What is the coefficient of variation?
The coefficient of variation is the ratio between the standard deviation and the mean.
Determine Coefficient of variation from the mean and standard deviation?
Coeff of Variation = Mean/SD
