结果1 题目If the standard deviation is large, it means the data is ___. 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...
就是 （计算的样本对象 减去 总体期望） 再除以 总体标准差。公式表示样本在总体中的位置。z-score=0表示恰好处于总体正态分布的中央位置，数值恰好等于数学期望。z-score=1就表示你问的“1 standard deviation above the average score”了...相当于“计算对象比数学期望高出一个标准差”的意思。其实...
Standard deviation measures the dispersion of data in relation to the mean, while standard error indicates the precision of the estimate of the sample mean. Here’s how to find them.

To figure out the variance: Divide the sum, 82.5, by either N (population variance) or N-1 (sample variance). In this example, N is 10 and N-1 would be 9. The result is a sample variance of 82.5/9 = 9.17 and a population variance of 8.25. Note that the standard deviation is...
