Definition:Standard Deviation (SD) is a statistical measure that captures the difference between the average and the outliers in a set of data. In other words, standard deviation measures how volatile a set of data is. What Does Standard Deviation Mean? Contents[show] What is the definition of...
A. the spread of the data around the mean B. the total number of data points C. the highest value in the data set D. the lowest value in the data set 相关知识点: 试题来源: 解析 A。“standard deviation”是标准差的意思,衡量数据围绕均值的分散程度。B 选项是数据点的总数;C 选项是数据...
What Does Standard Deviation Mean? Standard deviation measures how data is dispersed relative to its mean and is calculated as the square root of its variance. The further the data points are, the higher the deviation. Closer data points mean a lower deviation. In finance, standard deviation ca...
The standard deviation of a data set is a measurement of how close, in aggregate, its values are to the mean. The baseline from which this distance is measured is the mean of the data set. In short, a lower standard deviation means that the elements of the set are clustered mo...
Can deviation be negative? Yes, deviation can be negative if the value is below the mean or standard. 14 Is difference always a numerical value? No, difference can be qualitative, indicating dissimilarity, or quantitative, representing a numerical disparity. 14 What does deviation mean in statisti...
Also, as with any statistical model, large data sets are more reliable than small data sets. The 4.9% mean and 2.46% standard deviation in the example above is not as reliable as the same values produced from 50 calculations rather than five. So for the example above, 68% of the yearly...
Deviation is the difference between an individual data point and the mean of a dataset. 9 Does Standard Deviation account for direction? No, Standard Deviation does not account for the direction of deviation; it measures the magnitude of variability. 9 Can we compare datasets using Standard Deviat...

Given a mean of 8 and a standard deviation of 0.7, within how many standard deviations of the mean do the values 7.7, 8.4, 9, 8, and 6.9 fall? The mean of a list of numbers is 16.7 and the standard deviation is 0. What does this imply?
