![]() The histogram can be built for any series. ![]() The column's height corresponding expresses the amount of data allocated in each group (frequency) to this group. If it comes to the series, based on the qualitative attribute (for example, enterprises by their property category), these series are called attributive, if the series is built by quantitative attribute (for example, enterprises by their trade turnover), they are called variational.ĭepending on the continuity of the variation, there are discrete and interval variation series.Ī histogram is a bar graph constructed based on the findings, which are divided into several groups. Under the primary data in the statistics, we understand the statistical series, which is called time series when it comes to changing phenomena in time, or variation series when it comes to changing phenomena in time comes to the composition or structure of the investigated phenomenon. The grouping method is widely used for primary data processing. Generally speaking, the histogram is a graphic display of the grouping method, i.e., distributing the measurement set of some quantity into groups according to an important feature. Today I will talk about statistics and histograms.
