The reason N-2 is used rather than N-1 is that two parameters (the slope and the intercept) were estimated in order to estimate the sum of squares. Formulas for a sample comparable to the ones for a population are shown below.Show R code Question 1 out of 4. In a regression line,...
A sample of n = 100 scores has a mean of 30 and a variance of 36. What is the estimated standard error for the sample mean M? a. 3.6 b. 0.6 c. 5.0 d. 3.0 What z-score value separates the top 10% of a normal distribution from the bottom 90%?
Standard error of the meanIn most clinical and experimental studies, the standard deviation (SD) and the estimated standard error of the mean (SEM) are used to present the characteristics of sample data and to explain statistical analysis results. However, some authors occasionally muddle the ...
2) estimated standard error 估计标准误差 1. The calculation results show that the statistic and monitoring value are fairly identical, multiple correlation coefficients bigger and estimated standard error smaller. 计算结果表明:变形统计值与变形监测值吻合较好,统计复相关系数较大,估计标准误差较小。 更多...
The result is 0.835. The program then calculates an estimate of the standard error of the sample mean. The estimated standard error of the sample mean is closest to: 为什么0.835代表下面的公式这个又代表什么呢添加评论 0 0 1 个答案 已采纳答案 品职助教_七七 · 2023年12月03日 嗨,努力学习...
The standard error of the estimate measures the variability of the: A. predicted y-values around the mean of the observed y-values. B. values of the sample regression coefficient. C. actual dependent variable values about the estimated regression line. 相关知识点: 试题来源: 解析 C 略 反...
Relationship between Height-Weight Difference Index and Body-Fat Percentage Estimated by Bioelectrical Impedance Analysis in Thai Adults The best model was selected based on the determination coefficient (R.sup.2.sub.aj]), standard error of estimate ([S.sub.xy]), F value in 5% level of probabi...
C. actual dependent variable values about the estimated regression line. 正确答案:C 分享到: 答案解析: The standard error of the estimate (SEE) measures the uncertainty in the relationship between the independent and dependent variables and helps gauge the fit of the regression line (the smaller ...
Standard deviationandstandard errorare both used in statistical studies, including those in finance, medicine, biology, engineering, and psychology. In these studies, the SD and the estimated SEM are used to present the characteristics ofsampledata and explain statistical analysis results. ...
