Grouping and Ungrouping data in Kingsoft Spreadsheet is an effective way to keep consistent formatting. Grouping rows and columns of data is to tie a range of cells together so that they can be collapsed and expanded. Ungrouping rows or columns is done by selecting the previously grouped data range. In Kingsoft Spreatsheets, you can create an outline of up to eight levels for each group. Step 2.

However, in whatever job or scenario you use PDF Annotator, you will find the group and ungroup feature valuable. To begin, open a blank new document using the File, New command, and place several annotations or stamps on it, close together.

## Grouping and Ungrouping Annotations

This paper attempts to show in a non-mathematical way the influence of grouping on standard deviations and correlations, and advances empirical evidence to illustrate with what accuracy values corrected for grouping by Sheppard's correction approximate to values obtained from ungrouped data when the distributions are continuous. This enquiry gained its initial stimulus from the observation that many standard deviations and correlations reported by students of psychology and education are uncorrected for grouping and that frequently errors attributable to the grouping of data are not small when compared with errors of sampling.

Grouped data is a topic that goes back to the end of the nineteenth century at least. Kulldorff refers to grouping as a special case of a more general kind of procedure, called partial grouping. A partially grouped sample refers to the case where available information is associated with a collection of disjoint sets partitioning a domain. The sample space is divided into non-overlapping sets. In some of these sets only the counts of observations are recorded grouped data while the individual values of the observations falling in the other sets are recorded ungrouped data. This thesis focuses on spatially partially grouped data. This work is motivated by an interest in modeling the locations and times of wildfire occurrences that happened in the Continental United States in the period from to

## The application of Sheppard's correction for grouping

Grouped data are data formed by aggregating individual observations of a variable into groups, so that a frequency distribution of these groups serves as a convenient means of summarizing or analyzing the data. There are two major types of grouping: data binning of a single-dimensional variable, replacing individual numbers by counts in bins; and grouping multi-dimensional variables by some of the dimensions especially by independent variables , obtaining the distribution of ungrouped dimensions especially the dependent variables. The above data can be grouped in order to construct a frequency distribution in any of several ways.
