Data Analysis

In the previous post we have discussed about Associative Property of Addition and In today's session we are going to discuss about Data Analysis. The data analysis as the name suggests is just the analysis of the data. But we will look into the broader meaning of the term data analysis. The data analysis is a type of method which is generally used for enquiring about the data, cleaning the data, for taking the data from one place to another and also for data modeling. The motive of the data analysis that is the need of analyzing any type of the data is to get some vital information, to provide the conclusions and also to help in the process of making any type of the decision. (know more about Data analysis, here)
Let us take an example of the data analysis now. The mining of the data is also a special type of process of the data analysis which generally emphasizes on the modeling and on the discovery of the information for a motive which is predictive and not for any type of the purpose which is completely descriptive.
The term data analysis is also sometimes used in place of the ‘modeling of the data’. The data analysis is just a method under which various types of the phases can be separated. The data analysis is very much related to the visualization of the data.
Now we have seen the various definitions of the data analysis. So let us move on and study some further details of the data analysis. Therefore we will discuss now about the cleaning of the data which is nothing but only a part of the process of the data analysis. The cleaning of the data is a critical process under which the data is being enquired to check whether it is correct or not and finally the data which is found out to be incorrect are corrected if it is required.
