Ungrouped data 未分组数据 Grouped data 分组数据 分组数据最早指的是：分组交换是为适应计算机通信而发展起来的一种先进通信手段，它以CCITTX.25建议为基础，可以满足不同速率、不同型号终端与终端、终端与计算机、计算机与计算机间以及局域网间的通信，实现数据库资源共享。分组交换网是数据通信的基础网，...
Applying the median method to ungrouped data is made easier by doing the subsequent steps. Sort the data either in ascending or descending order. Second, count the overall ‘n’ number of observations. Verify whether ‘n’ is an even or an odd number of observations. When n is odd, the...
This is called raw data, or ungrouped data because it has not been sorted into any groups or categories. For example, imagine you're teaching a statistics course and you want to analyze the test scores of your students. You would first need to gather the scores, which initially would be...

摘要: Box and Cox (1964) proposed a power transformation which has proven utility for transforming ungrouped data to near normality. In this paper, we extend its applicability to grouped data. Illustrative examples are presented and the asymptotic properties of the estimators derived....
estimator computed from the original, ungrouped data. Two of the methodsrequiring grouped data are based on the minimum logit chi-square technique. The results, based on monte carlo simulation , are: (I) the grouped data methods often yield smaller mean squared errors when estimating 卤 and (...
