The process of Transforming, Cleaning, Inspecting, and modeling data, to get the best Data, supporting and Implementing this process is known as Data Analysis. It is a Process of Progressing Data by using logical and analytical reasoning, to validate each component of data offered. The method of analysis is one of the steps that completed when processing a research experiment. Data from many sources collected and analyzed to perform some set of conclusions and searching.

1.Data analysis:

Generally, It contains many phases. They are namely main data analysis, analysis, quality of measurement, quality analysis, and phase data cleaning.

a)Data Cleaning:

Known as starting the process of data analysis and Data cleaning and it records matching, column segmentation, duplication done to clean data from many sources.

b)Quality Analysis:

By using Frequency counts like descriptive options and statistics like standard deviation, frequency, kurtosis, skewness, normality histograms. Where the n variables are compared with the external data set.

2.Quality of measurements:

By using analysis of homogeneity and confirmatory factor analysis.


Generally, we have many varieties that can be done by starting the Data analysis phase. Box plots, Stem and leaf shows, Statistics like Kurtosis, skewness, variance, SD, M. Distribution, continuous variables, computing new variables. Exact examinations, bootstrapping in point of subgroups. Long linear analysis for recognizing important variables. 

3. Core Data analysis:

a)Implementing Confirmatory and exploratory approaches:

An Exploratory analysis, no clean hypothesis pointed before analyzing data and in a confirmatory analysis, clean hypothesis about the Data tested.

b)Stability of Outputs:

Stability of outputs by using validation, statistical analysis, sensitivity analysis.

3. Analysis by Implementing Statistical operations:

a)Linear Model:

Different Statistical models, the general linear model depends on MANCOVA, MANOVA, ANCOVA, ANOVA. As a matter of fact, this is known as a multi-linear regression sample generalization to the case of many Independent variables.

b)Structure Set of Equation Modelling:

Here they can access latent structures from scalable manifest variables. Item Response theory. For example, here samples implemented for accessing a single latent variable from many binary measured variables.

4. How to learn Data analysis:

At the same time, that you can explore the field of data analytics and this will help you in your total Job Journey. In the same fashion, you can learn qualitative and easy data analysis methods.

b)Challenges and Benefits of Data Analysis:

Finally, it is proved that data analysis tools are good and the best way for analyzing and gaining Data. By the Information provided by it, they can take better decisions and they serve their customers with more respect. 

These are the best-known ways that we can implement it, in further blogs, we will update more data on this Topic.
