no. it is the middle number. if u have the numbers 3, 12, and 5, u will have to put them in order from least to greatest. then u find the middle number which is 5. if u have more numbers like 23, 7, 34, 75, and 46, u would do this work:
order from least to greatest: 7, 23, 34, 46, 75
find the middle number: 5 numbers in total; 7, 23, 34,46, 75.

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.
Why standard deviation is best measure of dispersion?
standard deviation is best measure of dispersion because all the data distributions are nearer to the normal distribution.
What is the median is a measure of?
the median is the middle like 2,3,5,7,4,2.8. the median is 7 because it is in the middle.
Why is the median a more stable measure of central tendency than the mean?
in general,mean is more stable than median but in the case of extreme values it is better to consider median a stable measure than mean.
What is the importance of coefficient of variation?
It's a way of obtaining a measure of dispersion that is dimension-free.
What measure of dispersion is used with bimodal distribution?
Central tendency is used with bidmodal distribution. This measure if dispersion is similar to the median of a set of data.?æ
Which is the most accurate of mode mean median and range?
Accuracy depends on what you are trying to measure.As a measure of central tendency, the range is totally useless because it is not a measure of central tendency. As a measure of spread (dispersion), it is the most accurate because it is the only one that measures spread: the other threee are totally useless.With nominal data, the median and mean are not defined and so cannot be accurate.And so on.Accuracy depends on what you are trying to measure.As a measure of central tendency, the range is totally useless because it is not a measure of central tendency.

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.
Is range a measure of central tendency?
no it is a measure of dispersion.
What is measure of relative dispersion?
UPF
Why do you measure dispersion?
How do we calculate variance

Which is not a measure of dispersion range or variance?
Variance
What is dispersion method?
It is the measure of central tendency.
Why standard deviation is best measure of dispersion?
standard deviation is best measure of dispersion because all the data distributions are nearer to the normal distribution.
What is the median is a measure of?
the median is the middle like 2,3,5,7,4,2.8. the median is 7 because it is in the middle.
What are the characteristics of a good measure of dispersion?
A good measure of dispersion is one such that the a goodness-of-fit test shows that the observed values agree well with the expected values.
