Grouped data

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).

Find the Mean of Grouped Data | Statistics, Grouped Frequency Tables

How do we find the mean of grouped data? If we are given a grouped frequency table to represent data, that presents a challenge because we do not know the raw data values - we only know how many fall into certain groups. Thus, we are unable to calculate the mean the normal way. We'll go ov

Patrizio Frosini (8/30/21): On the role of group equivariant non-expansive operators in TDA

Group equivariant non-expansive operators (GENEOs) have been recently introduced as mathematical tools for approximating data observers, when data are represented by real-valued or vector-valued functions. The use of these operators is based on the assumption that the interpretation of dat
