“The standard deviation is a measure of the dispersion of a set of numbers.” In this statement, “standard deviation” is not similar to ___. A. mean deviation B. variance C. coefficient of variation D. arithmetic mean 相关知识点: 试题来源: 解析 D。“standard deviation”是标准差...
A. variance B. spread C. mean D. median 相关知识点: 试题来源: 解析 B。本题主要考查对标准差概念的理解。标准差是衡量数据分散程度的指标,也就是spread。选项 A 方差与标准差不同;选项 C 均值不是标准差的含义;选项 D 中位数也与标准差无关。反馈 收藏 ...
Standard Deviation:The standard deviation is a statistical measure that tells us how dispersed the data in a set are in relation to its mean. There are two formulations for standard deviation, one for a sample and the other for a population. We can calculate the standard deviation using the ...
A national consensus is used to find out information about the nation's citizens. By definition, it includes the whole population. Therefore, a population standard deviation would be used. What are the formulas for the standard deviation? The sample standard deviation formula is: where, s = ...
Note that the standard deviation is the square root of the variance, so the standard deviation is about 3.03 for a sample data set. The standard deviation for a population data set would be 2.87. The sample formula is used when the data set represents a random sample from the entire pop...
A. central tendency B. variability C. symmetry D. skewness 相关知识点: 试题来源: 解析 B。A 选项 central tendency 中心趋势。B 选项 variability 变异性,标准差是衡量数据离散程度,即变异性的指标,符合题意。C 选项 symmetry 对称性。D 选项 skewness 偏度。反馈 收藏 ...
