What else can I help you with?
What is considered measures of variabilty is it mean interquartile range or mean absolute deviation?
interquartile range or mean absolute deviation.
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.
What is a measure of the spread of a set of data?
The standard deviation is the value most used. Others are variance, interquartile range, or range.
What do the quartile deviation and the interquartile range describe?
The quartile deviation and the interquartile range (IQR) both describe the spread of the middle 50% of a dataset. The IQR is calculated as the difference between the third quartile (Q3) and the first quartile (Q1), providing a measure of variability that is less affected by outliers. The quartile deviation, on the other hand, is half of the IQR and represents the average distance of data points from the median, offering a sense of dispersion around the center of the dataset. Together, they help assess the distribution and consistency of the data.
How do you find the interquartile range when given the mean and standard deviation?
In general you cannot. You will need to know more about the distribution of the variable - you cannot assume that the distribution is uniform or Normal.
What is considered measures of variabilty is it mean interquartile range or mean absolute deviation?
interquartile range or mean absolute deviation.
Does an outlier have a greater effect on the standard deviation or interquartile range?
On the standard deviation. It has no effect on the IQR.

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.
What are the common measures of dispersion?
Range, standard deviation, variance, root mean square, interquartile range
What does interquartile range mean?
The interquartile range is the upper quartile (75th percentile) minus (-) the lower percentile (75th percentile). The interquartile range uses 50% of the data. It is a measure of the "central tendency" just like the standard deviation. A small interquartile range means that most of the values lie close to each other.
What is a measure of the spread of a set of data?
The standard deviation is the value most used. Others are variance, interquartile range, or range.
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 is the interquartile range of 16171922232527363840404546?
what is the interquartile range of 16,17,19,22,23,25,27,36,38,40,40,45,46
Why is the interquartile range a more appropriate measure for spread than the range?
the interquartile range is not sensitive to outliers.
What do you mean by measures of central tendency and dispersion?
Common measures of central tendency are the mean, median, mode. Common measures of dispersion are range, interquartile range, variance, standard deviation.
How do you find the semi-interquartile range with only the mean and standard deviation?
In general, you cannot. If the distribution can be assumed to be Gaussian [Normal] then you could use z-scores.
