Their mathematical formulation is also well known along with their associated stereotypical examples (e.g., Harmonic mea...Sun, 05 Apr 2026 19:32:00 GMThttps://stats.stackexchange.com/questions/148868/difference-in-means-vs-mean-differenceWhen studying two independent samples means, we are told we are looking at the "difference of two means". This means we take the mean from population 1 ($\\bar y_1$) and subtract from it the mean fromSun, 05 Apr 2026 10:28:00 GMThttps://stats.stackexchange.com/questions/659643/why-is-standard-deviation-preferred-over-absolute-deviations-from-the-meanThe mean is the number that minimizes the sum of squared deviations. Absolute mean deviation achieves point (1), and absolute median deviation achieves both points (1) and (3).Mon, 23 Mar 2026 14:47:00 GMThttps://stats.stackexchange.com/questions/239379/what-is-the-difference-between-mean-squared-deviation-and-varianceI also guess that some people prefer using mean squared deviation as a name for variance because it is more descriptive -- you instantly know from the name what someone is talking about, while for understanding what variance is you need to know at least elementary statistics. Check the following threads to learn more:Sun, 05 Apr 2026 12:37:00 GMThttps://stats.stackexchange.com/questions/319637/how-to-read-scientific-notation-output-numbers-that-include-eWhat does the notation like 8.6e-28 mean? What is the 'e' for? (2 answers) Closed 8 years ago. After running the lm regression model using R, sometime one is bound to get very small P values or values in the covariance matrix. Something of the sort: -1.861246e-04 for example in a covariance matrix.Sat, 04 Apr 2026 07:59:00 GMThttps://stats.stackexchange.com/questions/625849/how-to-calculate-standard-deviation-when-only-mean-of-the-data-and-sample-size-iYou may note that most of these distributions depend on only one parameter. I would conjecture that actually most single-parameter distributions for which closed-form solutions for both mean and variance exist allow you to deduce the standard deviation from the mean. So this table is probably incomplete.Fri, 27 Mar 2026 18:03:00 GMThttps://stats.stackexchange.com/questions/206081/what-is-implied-by-standard-deviation-being-much-larger-than-the-meanWhat does it imply for standard deviation being more than twice the mean? Our data is timing data from event durations and so strictly positive. (Sometimes very small negatives show up due to clockSun, 05 Apr 2026 20:58:00 GMThttps://stats.stackexchange.com/questions/1063/why-are-mean-0-and-standard-deviation-1-distributions-always-usedThe mean of 0 and standard deviation of 1 usually applies to the standard normal distribution, often called the bell curve. The most likely value is the mean and it falls off as you get farther away.Tue, 31 Mar 2026 19:17:00 GMThttps://www.zhihu.com/question/20509354mean 表示是观测值的平均值,只考虑数据集中出现的所有数据. 符合 正太分布. median 表示数据集的数据范围的中间值. 符合 偏态分布 举个例子, 如果有两个公司, 某岗位的工资的median value 相差不大,A公司员工的工资的mean value 大于大于B公司员工工资mean value, 说明A公司有部分员工工资特别高. 所以以后找 ...Wed, 25 Mar 2026 22:52:00 GMT
