range

The IQR gives the range of the middle half of the data and, in that respect, it is a measure of the variability of the data.

The standard deviation is better since it takes account of all the information in the data set. However, the range is quick and easy to compute.

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.

In a small data set, the range. However, I would not like to try and find the range for the volume of rain drops, or the size of sand grains!

The range, inter-quartile range (IQR), mean absolute deviation [from the mean], variance and standard deviation are some of the many measures of variability.

Variability

it is a range of variations between cultures.

No, it does not

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.

The measure of variability tells you how close to the central value the data values lie: that is whether the cluster is tightly packed around the central value of spread out over a large range of values.

Variability is a measure of differences between multiple observations. These may be observations of a number of different objects or repeated observations on the same object.

Because answer will definitely fall within the range but not necessarily group together evenly throughout the whole range.

The range is most distorted.

An indication of how widely spread or closely clustered the data values are. Range, minimum and maximum values, and clusters in distribution give some indication of variability.

It measures the error or variability in predicting Y.

The range is very sensitive to outliers. Indeed if there are outliers then the range will be unrelated to any other elements of the sample.

It is a measure of how much a measure [of a variable] can change.

Yes.
