Visualization techniques are ways of creating and manipulating graphical representations of data. Many people find frequency tables, crosstabs, and other forms of numerical statistical results intimidating. When creating and editing graphs, it is important to make sure the graphs do not get distorted. It also uses the geometrical symbol to show the rapid visualisation of the data set. The graphic presentation of data and information offers a quick and simple way of understanding the features and drawing comparisons. Facts and figures as such do not catch our attention unless they are presented in an interesting way. Graphical representation is the visual display of data using plots and charts. A chart can represent tabular numeric data, functions or some kinds of quality structure and provides different info. Since line graphs are very light-weight (they only consist of lines, as opposed to more complex chart types, as shown further below), they are great for a minimalistic look. it is used in many academic and professional disciplines but most widely so in the field of mathamatics,medicine and the science. Generally, statisticians use four methods to represents the frequency distribution graphically. The purpose of a graph is a rapid visualization of a data set. The Importance of Graphical Data Representation. The graphic presentation of data and information offers a quick and simple way of understanding the features and drawing comparisons. This is the perfect solution for showing multiple series of closely related series of data. Graphical representation helps to quantify, sort and present data in a method that is understandable to a large variety of audiences. In Focus. Bar diagram 4. Graphical representation enables the quick analysis of large amounts of data at one time and can aid in making predictions and informed decisions. Advantages of scatterplots are that they can demonstrate associations between two variables, they retain the exact data values (including minimum and maximum values), and that they may make outliers apparent. Other graph types such as pie charts are possible for quantitative data. It always depends on the type of information in a particular domain. , we can find different measures of central tendency like mean, median, mode, variance and standard deviation.
