What describes the spread of data?
Range, variance, and standard deviation usually are used to describes the spread of data.
Why is standard deviation best when there are outliers?
Standard deviation is often preferred for measuring variability in datasets with outliers because it takes into account the dispersion of all data points, providing a comprehensive view of variability. Unlike range or interquartile range, which can be heavily influenced by extreme values, standard deviation assesses how far each data point deviates from the mean. This makes it useful in identifying the overall spread of data, even when outliers are present. Additionally, standard deviation helps in understanding the data's distribution shape, which can be crucial in statistical analyses.
Can the value for the standard deviation be larger than the value for the rqange?
Yes, the standard deviation can be larger than the range in certain situations. The range is calculated as the difference between the maximum and minimum values in a dataset, while the standard deviation measures the spread of the data around the mean. If the data points are widely dispersed with a few extreme values, the standard deviation can exceed the range, especially in small datasets.
How do you calculate sample standard deviation?
Here's how you do it in Excel: use the function =STDEV(<range with data>). That function calculates standard deviation for a sample.

What is the range of standard deviation of 18 15 12 13 17 14 19 20 8?
The range is 12 and the standard deviation is 3.822448314.
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.
Find the range and standard deviation of the data set. 22 18 19 25 27 21 24?
The range is 9 and 3.01 is the standard deviation.

The standard deviation = 23.856
Is the range used to compute the median or standard deviation?
Neither.
What is a better measure of variability range or standard deviation?
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.
How do you calculate plus or minus one standard deviation?
To calculate plus or minus one standard deviation from a mean, first determine the mean (average) of your data set. Then calculate the standard deviation, which measures the dispersion of the data points around the mean. Once you have both values, you can find the range by adding and subtracting the standard deviation from the mean: the lower limit is the mean minus one standard deviation, and the upper limit is the mean plus one standard deviation. This range contains approximately 68% of the data in a normal distribution.
