What is percentile deviation?
A standard deviation in statistics is the amount at which a large number of given values in a set might deviate from the average. A percentile deviation represents this deviation as a percentage of the range.
Can a standard deviation of 4.34 be correct?
Yes, a standard deviation of 4.34 can be correct. Standard deviation is a measure of dispersion or variability in a data set. It represents the average amount by which individual data points deviate from the mean. Therefore, a standard deviation of 4.34 simply indicates that there is some variability in the data, with data points on average deviating by 4.34 units from the mean.
What is standard abbreviation to standard deviation?
The standard abbreviation for standard deviation is "SD." It is commonly used in statistical analysis to represent the amount of variation or dispersion in a set of values.
What is the relationship between standard deviation and mean?
The standard deviation and mean are both key statistical measures that describe a dataset. The mean represents the average value of the data, while the standard deviation quantifies the amount of variation or dispersion around that mean. A low standard deviation indicates that the data points are close to the mean, while a high standard deviation indicates that they are spread out over a wider range of values. Together, they provide insights into the distribution and variability of the dataset.
How does standard deviation depend on a data?
Standard deviation measures the amount of variation or dispersion in a dataset. It quantifies how much individual data points deviate from the mean of the dataset. A larger standard deviation indicates that data points are spread out over a wider range of values, while a smaller standard deviation suggests that they are closer to the mean. Thus, the standard deviation is directly influenced by the values and distribution of the data points.
What statistic is the average amount by which the scores in a distribution vary from the mean?
Standard deviation

How To Calculate Standard Deviation?
You can calculate standard deviation by addin the numbers of data that are together and dividing that number by the amount pieces of data.THAT IS TOTALLY INCORRECT.What was answered above was the calculation for getting an (mean) average.If you take five numbers for example 1, 2, 3, 4, 5 then the (mean) average is 3.But the standard deviation between them is 1.58814 and the variance is 2.5Also the population std. deviation will be 1.41421 and the population variance will be 2.see standard-deviation.appspot.com/
Why variance is bigger than standard deviation?
The variance is standard deviation squared, or, in other terms, the standard deviation is the square root of the variance. In many cases, this means that the variance is bigger than the standard deviation - but not always, it depends on the specific values.
How does standard deviation depend on a data?
Standard deviation measures the amount of variation or dispersion in a dataset. It quantifies how much individual data points deviate from the mean of the dataset.

Thus, the standard deviation is directly influenced by the values and distribution of the data points.
What is the s d?
Standard deviation (SD) is a measure of the amount of variation or dispersion in a set of values. It quantifies how spread out the values in a data set are from the mean. A larger standard deviation indicates greater variability, while a smaller standard deviation indicates more consistency.
Can you have a standard deviation of 435000?
Yes, a standard deviation of 435,000 is possible and indicates a high level of dispersion in a dataset. Standard deviation measures the amount of variation or spread in a set of values; thus, if the data points are widely spread apart from the mean, a large standard deviation can occur. This could be typical in datasets with large values, such as income or real estate prices.
What does large standard deviation signify?
That there is quite a large amount of variation between the observations.
The average amount customers at a certain grocery store spend yearly is 636.55 Assume the variable is normally distributed If the standard deviation is 89.46 find the probability that a randomly?
.820=82.0%
