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 ...
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...
A. consistent B. homogeneous C. diverse D. similar 相关知识点: 试题来源: 解析 C。如果标准差大,意味着数据是多样的,diverse。选项 A 一致的不符合大标准差的情况;选项 B 同质的也不对;选项 D 相似的也不是大标准差的表现。反馈 收藏
A. central tendency B. dispersion C. frequency D. correlation 相关知识点: 试题来源: 解析 B。本题考查统计学中标准偏差的概念。标准偏差是用来衡量数据的离散程度,即分散程度,选项 A 中心趋势通常由均值、中位数等表示;选项 C 频率指某个值出现的次数;选项 D 相关性用于描述两个变量之间的关系。反馈...
