A histogramis a visual representation of the distributionof quantitative data. To construct a histogram, the first step is to "bin" (or "bucket")the range of values— divide the entire range of values into a series of intervals—and then count how many values fall into each interval. The bins are usually specified as consecutive, non ...
Data presentation architecture (DPA) is a skill-set that seeks to identify, locate, manipulate, format and present data in such a way as to optimally communicate meaning and proper knowledge. Historically, the term data presentation architecture is attributed to Kelly Lautt: [ a ] "Data Presentation Architecture (DPA) is a rarely applied skill ...
A histogram is a representation of tabulated frequencies, shown as adjacent rectangles or squares (in some of situations), erected over discrete intervals (bins), with an area proportional to the frequency of the observations in the interval. The height of a rectangle is also equal to the frequency density of the interval, i.e., the frequency ...
Research. A descriptive statistic (in the count noun sense) is a summary statistic that quantitatively describes or summarizes features from a collection of information, [1] while descriptive statistics (in the mass noun sense) is the process of using and analysing those statistics. Descriptive statistics is distinguished from inferential ...
A dose-volume histogram (DVH) is a histogram relating radiation dose to tissue volume in radiation therapy planning. [1] DVHs are most commonly used as a plan evaluation tool and to compare doses from different plans or to structures. [2] DVHs were introduced by Michael Goitein (who introduced radiation therapy concepts such as the "beam's-eye ...
e. In statistics, exploratory data analysis (EDA) is an approach of analyzing data sets to summarize their main characteristics, often using statistical graphics and other data visualization methods. A statistical model can be used or not, but primarily EDA is for seeing what the data can tell us beyond the formal modeling and thereby contrasts ...
encourage the eye to compare different pieces of data. reveal the data at several levels of detail, from a broad overview to the fine structure. serve a reasonably clear purpose: description, exploration, tabulation, or decoration. be closely integrated with the statistical and verbal descriptions of a data set.
Statistics is a mathematical body of science that pertains to the collection, analysis, interpretation or explanation, and presentation of data,[5]or as a branch of mathematics.[6] Some consider statistics to be a distinct mathematical sciencerather than a branch of mathematics. While many scientific investigations make use of data, statistics ...
