StatisticsZ-14: Estimating Analytical Errors Using Regression Statistics Z-Stats / Basic Statistics Z-14: Estimating Analytical Errors Using difference between absolute and relative error Regression Statistics Written by Madelon F. Zady. Enough of this abstract statistical stuff: how do we use these things in the laboratory? This article shows you the## Constant Systematic Error

practical application of statistics on the bench-level, including how to find the bias and other important stats. EdD, Assistant ProfessorClinical Laboratory Science Program, University of LouisvilleLouisville, KentuckyOctober 2000 Review of the regression model Standard error of regression and random error Y-intercept and constant systematic error Slope and proportional systematic error Bias and overall systematic error types of errors in analytical chemistry ppt Problems with regression References In the previous lesson, we described regression in the classical fashion. In this lesson, we will describe practical laboratory applications and some of the complications encountered when working with real experimental data. The language and applications of regression are all around us in the laboratory, particularly in the established practices for method validation and quality control. Terms such as Bias, (Ybar-Xbar), [(bXbar + a) - Xbar], slope, intercept, and Sy/x to name just a few, all derive from regression terminology. In this lesson, we will illustrate how regression statistics can be used to estimate the analytical errors occurring with a laboratory method. We'll focus on a comparison of methods experiment, which is commonly used to validate that a new method provides results consistent with the old method that is being replaced. Review of the regression model In the last lesson, we looked at the derivation of the slope coefficient of the regression line from the deviation scoreFacts Branding Guidelines Contact What Parents Should Know Standards in Your State Read the Standards English Language Arts Standards Mathematics Standards Other Resources Key Shifts in English Language

For example, if a person walks https://www.westgard.com/lesson44.htm 1/2 mile in each 1/4 hour, compute the unit rate as the complex fraction 1/2/1/4 miles per hour, equivalently 2 miles per hour.CCSS.Math.Content.7.RP.A.2Recognize and represent proportional relationships between quantities.CCSS.Math.Content.7.RP.A.2.aDecide whether two quantities are in a proportional relationship, e.g., by testing for equivalent ratios in a table or graphing on a coordinate plane and observing whether the graph is a straight http://www.corestandards.org/Math/Content/7/RP/ line through the origin.CCSS.Math.Content.7.RP.A.2.bIdentify the constant of proportionality (unit rate) in tables, graphs, equations, diagrams, and verbal descriptions of proportional relationships.CCSS.Math.Content.7.RP.A.2.cRepresent proportional relationships by equations. For example, if total cost t is proportional to the number n of items purchased at a constant price p, the relationship between the total cost and the number of items can be expressed as t = pn.CCSS.Math.Content.7.RP.A.2.dExplain what a point (x, y) on the graph of a proportional relationship means in terms of the situation, with special attention to the points (0, 0) and (1, r) where r is the unit rate.CCSS.Math.Content.7.RP.A.3Use proportional relationships to solve multistep ratio and percent problems. Examples: simple interest, tax, markups and markdowns, gratuities and commissions, fees, percent increase and decrease, percent error.
