Methods of data representation

There are several methods of data representation in statistics help used for represent the data in a specified manner also known as the data display. Data representation methods is arrangement of data that is provide the visualization of the data in tabulated form or in form of graphs or charts or maps or diagrams . Also improve your knowledge solving Data Set Example.
We can elaborate some basic needs for data representation:
(1) : difficulties in understanding the descriptive data that is not very easily draw for the results.
(2) : for making or drawing the visual impression of the data that is provide the more ease .
(3) : Helps in doing comparison between data very easily .
(4) : Characteristics representation can be done in a simplified way .
1.
5. : Representation makes process easy for some types of patterns that are as population growth, distribution and density or age – sex composition etc.
So there are some Data representation methods as follows:
(a) data will be represented in the tabular form means all the data is maintained in the tables that will help in understand the data with all its attribute that are also known as the properties of the data .
(b) For representing the data there one more technique that is known as graphs and one of these are pie charts that will provide the way for understanding that how data is changed in the particular environment that is depends on some other variable for specific experiment .
(c) There is one another type of representation of data that is drawing some charts.
(d) The graphs that is used in data representation have categorize in some types that are define as line graph or histogram or bar graph or pyramids etc.

In upcoming posts we will discuss about Correlation and causation and Mathematical induction. Visit our website for information on state board of Maharashtra syllabus
