Data mining is a particular data analysis technique that focuses on statistical modeling and knowledge discovery for predictive rather than purely descriptive purposes, while business intelligence covers data analysis that relies heavily on aggregation, focusing mainly on business information. [4]
Exploratory data analysis (EDA) is an approach to analyzing data sets to summarize their main characteristics, often with visual methods. A statistical model can be used or not, but primarily EDA is for seeing what the data can tell us beyond the formal modeling or hypothesis testing task.
The entry age in class 1 is 5+. Pre-primary classes form age group 3 to 4. The higher secondary school certificate enables pupils to pursue studies either in universities or in colleges for higher education in general academic streams and in technical and professional courses.

It is essential to carry the study based on the three basic principles of experimental statistics: randomization , replication , and local control.
Exploratory data analysis is an analysis technique to analyze and investigate the data set and summarize the main characteristics of the dataset. Main advantage of EDA is providing the data visualization of data after conducting the analysis.
As a part of the tenth Five-year Plan (2002–2007), the central government of India outlined an expenditure of 65.6% of its total education budget of ₹ 438 billion (US$5.1 billion) i.e. ₹ 288 billion (US$3.4 billion) on elementary education; 9.9% i.e. ₹ 43.25 billion (US$510 million) on secondary education; 2.9% i.e. ₹ 12.5 billion (US ...
Data modeling during systems analysis: In systems analysis logical data models are created as part of the development of new databases. Data modeling is also used as a technique for detailing business requirements for specific databases .
However, this technique has been shown to yield poorly calibrated models, with an overestimated probability to belong to the minority class. [5] To illustrate how this technique works consider some training data which has s samples, and f features in the feature space of the data. Note that these features, for simplicity, are continuous.
