SamplingDistribution(抽样分布): Statisticians make Statistical Inference by constructing Sampling Distributions from the Statistics of Sample(Sample Mean, Proportion, and so on)。these distributions assures Accuracy and Reliability while inference Parameters of Population from Samples. ErrorEstimation(误差估计):...

Calculate the Statistics of Testing: 根据选定检验方法从样本数据计算对应的Statistics of Testing(检验统计量), 以反映 Sample(样本数据) 与 H0零假设的一致性程度。 Decision-Making: 比较Statistics of Testing 与α(Significance Level), 判断是否有足够的证据拒绝H0零假设。 如果Statistics of Testing 显示的差异...
Population vs Sample Statistics Statisticians refer to population values asparametersand sample values as statistics. Learn more aboutParameters vs Statistics: Examples & Differences. Population parameters are precise but typically unknown values. For example, the population mean height for all U.S. women...
由population 反应既数据通常都under normal distribution. sample 系细数目既统计数据 (eg. 小于10个data). 反应既数据唔会系一个靓既normal distribution curve. 如果用normal distribution 去estimate sample 既data 就唔会太准~ 所以sample statistics 会有另外既formula.参考: cliffsnotes/WileyCDA/...

Research example: Parameters and statisticsIn your study of students’ political attitudes, you ask your survey participants to rate themselves on a scale from 1, very liberal, to 7, very conservative. You find that most of your sample identifies as liberal – the mean rating on the political...
In the case of such representative sample, the population parameters can be estimated from the sample values. These interpretive difficulties arise when you try to draw conclusions about a population parameter from a sample statistic. A point estimate is a one-number estimate of the value of a ...
