What is data analysis

The 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 analysed to perform some set of conclusion and searching. We have many varieties of data analysis methods. In that, some of them contain data mining, data visualizations, and business Intelligence. In this blog what is Data analysis we will discuss more updates on it.

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

Now we will go step by step

Data cleaning

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

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 external data set.

Quality of measurements

By using analysis of homogeneity and confirmatory factor analysis.


Generally, we have many varieties that can be done by starting 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. Hierarchical log linear analysis, circumambulations, associations, percentages, frequency counts in numbers. Ordinal and nominal variables. Graphical techniques that scatter plots. Bi variate Associations correlations, uni variate statistics and one variable.

Core Data analysis

Implementing Confirmatory and exploratory approaches

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

Stability of Outputs

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

Analysis by Implementing Statistical operations

Linear Model

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

Structure Set of Equation Modelling, They can assess latent structures from scalable manifest variables. Item Response theory. For example, here samples implemented for assessing single latent variable from many binary measured variables.

Data Analysis Approaches, Cross-cultural analysis, content, grounded theory, Discourse analysis, hermeneutic, constant comparative analysis, Phenomenological analysis, narrative analysis.
