What describes the spread of data?
Range, variance, and standard deviation usually are used to describes the spread of data.
Is the range used to compute the median or standard deviation?
Neither.
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 and standard deviation of 26 43 51 29 37 56 29 82 74 93?
The standard deviation = 23.856
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.

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.
Is the range used to compute the median or standard deviation?
Neither.

The standard deviation = 23.856
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.
In research how to define standard deviation?
Standard deviation shows how much variation there is from the "average" (mean). A low standard deviation indicates that the data points tend to be very close to the mean, whereas high standard deviation indicates that the data are spread out over a large range of values.
Why range is considered as good measure of variability and why standard deviation is preferred over the other?
Range is considered a good measure of variability because it provides a simple and quick assessment of the spread of data by capturing the difference between the maximum and minimum values. However, it is sensitive to outliers and does not account for the distribution of values between the extremes. Standard deviation is preferred because it considers how each data point deviates from the mean, providing a more comprehensive view of variability, and it is less influenced by extreme values. This makes standard deviation a more robust and informative measure for understanding the dispersion of data.
