Comparing More Than Two Groups

Analysis of Variance (ANOVA)

One of the hallmarks of statistical thinking is the importance of measuring and understanding variability. The Shewhart Control Chart, which separates special cause from common cause variation, is one of the most important tools for understanding the current state of a process. The analysis of variance (ANOVA) is another statistical tool for splitting variability into component sources. These c...

A practical approach for comparing means of two groups without equal variance assumption.

In this paper we consider two-groups of i.i.d. normally distributed random variables (N(mu(x),sigma(x) (2)) and N(mu(y),sigma(y) (2))) without assuming equal variance (sigma(x) (2) = sigma(y) (2)). We propose a simple method for constructing confidence bounds based on Howe's approximation I. Its applications in parallel clinical trial (testing H(0) : mu(x)-mu(y)=0 versus H(1) : mu(x)-mu(y)<0) a...

چکیده گفتگوگری باختین نظریه ای است که به تفاوت ها احترام گذاشته و گفتگو را ارج می نهد. رشته های مختلف علوم انسانی همواره از این نظریه بهره جسته اند. با وجود این تنها مطالعات اندکی در زمینه تجزیه و تحلیل نقادانه کلام به نظریه گفتگوگری پرداخته اند. پنداشت تحقیق حاضر بر آن است که احترام به حقوق دیگران از طریق فراهم آوردن شرایط یکسان برای بیان نظریات مختلف یکی از مهمترین مشترکات تحلیل انتقادی گفتم...
