What is a disadvantage of using the range as a measure of variation?

What is a disadvantage of using the range as a measure of variation?

What is a disadvantage of using the range as a measure of​ variation? The units of variance are squared. Its units are meaningless. When calculating the population standard​ deviation, the sum of the squared deviation is divided by​ N, then the square root of the result is taken.

What is the disadvantage of the range?

The disadvantage of using range is that it does not measure the spread of the majority of values in a data set-it only measures the spread between highest and lowest values. As a result, other measures are required in order to give a better picture of the data spread.

Why is the range not a good measure of variability?

The range is a poor measure of variability because it is very insensitive. By insensitive, we mean the range is unaffected by changes to any of the middle scores. As long as the highest score (i.e., 6) and the lowest score (i.e., 0) do not change, the range does not change.

How does range affect variability?

The range tells you the spread of your data from the lowest to the highest value in the distribution. It’s the easiest measure of variability to calculate. Because only 2 numbers are used, the range is influenced by outliers and doesn’t give you any information about the distribution of values.

What is the disadvantage of the range as a measure of dispersion quizlet?

What is a disadvantage of the range as a measure of dispersion? It is based on only two observations.

What is the primary disadvantage of using the range rather than the variance to compare the variability of two data sets?

What is the primary disadvantage of using the range to compare the variability of data​ sets? It is a rather insensitive measure of data variation. Describe the sample variance using words rather than a formula. Variance can be smaller than the standard deviation if the variance is less than 1.

What is a disadvantage of the range as a measure of dispersion quizlet?

What is a disadvantage of the range as a measure of dispersion? It is based on only two observations. Which measure of dispersion disregards the algebraic signs (plus and minus) of each difference between X and the mean?

Which of the following is a disadvantage of using the sample range to measures of spread or dispersion *?

The disadvantage of range is that it is extremely sensitive to outliers.

What are two problems with range as a measure of variability?

The problem with using the range as a measure of variability is that it is completely determined by two extreme values and ignore the other scores in the distribution. Thus, a distribution with one unusually large score has a large range even if the other scores are all clustered together.

Why is the standard deviation preferable to the range as a measure of variation?

The standard deviation is preferable to the range as a measure of variation because the standard deviation takes into account all of the​ observations, whereas the range considers only the largest and smallest ones.

What is measure variability?

Variability refers to the spread, or dispersion, of a group of scores. Measures of variability (sometimes called measures of dispersion) provide descriptive information about the dispersion of scores within data. Common measures of variability include range, variance, and standard deviation.

Is range a measure of spread?

Measures of spread include the range, quartiles and the interquartile range, variance and standard deviation.
