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，...
Raw data is ungrouped, and has not been sorted, whereas grouped data is formatted into organized groups by specific categories. Explore the distinctions between grouped and ungrouped data through several examples of each. What Is Data? Suppose you decided to record the temperature outside your ho...
The median of the provided data could be determined using the following set of calculations. How to Calculate Median for Grouped Data The continuous data that is shown as a frequency distribution is the median of the grouped data. The centre number in the set of data, known as the median...

Maximum likelihood estimates of the parameters were obtained using both grouped and ungrouped data; for the three parameter cases and the two parameter grouped data cases, the method of scoring worked well. Comparison of the efficiencies of the estimates using grouped data showed that logarithmic ...

By estimating the first stage using the available individual data, and then estimating the second stage at the aggregate level, it might be possible to gain efficiency relative to the OLS and 2SLS estimators that use only grouped data. We term this the mixed-2SLS estimator (M2SLS). The M...
