Is range a measure of central tendency?
no it is a measure of dispersion.
Which is not a measure of dispersion range or variance?
Variance
Why is range not a measure of central tendency?
Measures of central tendency are averages. Range , the difference between the maximum and the minimum, is a measure of dispersion or variation.
What are measures of dispersion in healthcare?
It's a statistical tool used in psychology. A simple way of calculating the measure of dispersion is to calculate the range. The range is the difference between the smallest and largest value in a set of scores. This is a fairly crude measure of dispersion as any one high or low scale can distort the data. A more sophisticated measure of dispersion is the standard deviation which tells you how much on average scores differ from the mean.
Is the range a measure of dispersion that is the least sensitive to extreme value of the data set?
the range is the total number of values your set can take. If you take all the number from 5 to 25. Your range is 5-25.
Is a disadvantage of the range as a measure of dispersion based on only 2 observations max and minimum?
yes
Is a disadvantage of the range as a measure of dispersion a) based on only two observations b) can be distorted by a large mean c) not in the same units as the original data d) has no disadvantage?
A disadvantage of the range as a measure of dispersion is a) based on only two observations. The range is calculated using only the maximum and minimum values of a dataset, which means it does not account for the distribution of the other values. This limited perspective can lead to a misleading representation of the overall variability within the data.
Is range a measure of central tendency?
no it is a measure of dispersion.
Which is not a measure of dispersion range or variance?
Variance
Advantage and disadvantage of range?
The advantage of range in a set of data is that it provides a simple measure of the spread or dispersion of the values. It is easy to calculate by subtracting the minimum value from the maximum value. However, the disadvantage of range is that it is heavily influenced by outliers, as it only considers the two extreme values and may not accurately represent the variability of the entire dataset. For a more robust measure of dispersion, other statistical measures such as standard deviation or interquartile range may be more appropriate.
What is the disadvantage of the range as a measure of dispersion?
The range, defined as the difference between the maximum and minimum values in a dataset, has several disadvantages as a measure of dispersion. Primarily, it is highly sensitive to outliers, meaning a single extreme value can significantly distort the range and provide a misleading representation of variability. Additionally, the range does not account for how the data points are distributed within the dataset, failing to reflect the overall spread or clustering of values. This limited perspective makes it less informative compared to other measures of dispersion, such as the interquartile range or standard deviation.
Why is range not a measure of central tendency?
Measures of central tendency are averages. Range , the difference between the maximum and the minimum, is a measure of dispersion or variation.
What are the whiskers of a box plot?
They are some measure of the dispersion or range of numbers in the set of data.

What is the interquartile range a measure of?
The interquartile range is well known as a measure of statistical dispersion. It is equal to difference between upper and lower quartiles. The quartiles is a type of quantile.
What is the disadvantage of using range as a measure of dispersion?
It only tells you about the max and min values. It would be good to know about what happens in between them. For example, you can all one very big value to a data set and change the range dramatically. The rest of the data remains the same, but you would not know that.
What is the semi interquartile range?
The semi interquartile range is a measure for spread or dispersion. To find it you have to subtract the first quartile from Q3 and divide that by 2, (Q3 - Q1)/2
