Avinash attended Class 9 Tuition
"Praveen sir took maths classes for my daughter. He has a very good subject and practical knowledge. He genuinely took interest in bringing out the talent in her and helped her to score high marks in the exam.Thank you so much. "
B. Chandraa attended Class 11 Tuition
"He is very precise when he takes classes. Not only is he regular ( since he plans his classes on the bases of the students level of understanding) but he also makes sure the student thoroughly understands what he or she wants to learn. He very helpfully coaches you with questions that recur in exams ( and weirdly most of the time you get only those). He uses practical examples without only depending on the book. Cool- headed and sincere, he tells you all you need to know especially when it comes to his subjects ( physics, math and computer science). If you want to cover large portions in a short amount of time , not only studying but learning , he is perfect. "
Santhosh attended C++ Language
"A very friendly tutor. Lots of knowledge about the subject. The way he explains about the concepts using the day to day life applications makes the learning more interactive and interesting. "
Abyan mohammed attended Class 11 Tuition
"Mr.Praveen is a very friendly person. I enjoyed his classes and benefited very well from the classes. I was able to understand concepts better with him. He is a punctual person. His classes are not boring or dull, he was able to keep things light and still manage to cover all topics. "

Rank correlation is more precise than simple correlation coefficient in the following situations
(i) When the Measurements of the Variables are Suspect In a remote village, where measuring rods or weighing scales are not available, height and weight of people cannot be measured precisely but the people can be easily ranked in terms of height and weight.
(ii) When Data is Qualitative It is difficult to quantify qualities such as fairness, honesty, etc. Ranking may be a better alternative to quantification of qualities.
(iii) When Data has Extreme Values Sometimes the correlation coefficient between two variables with extreme values may be quite different from the coefficient without the extreme values. Under these circumstances rank correlation provides a better alternative to simple correlation.

It is essential to have different CPI for different categories of consumers as each categories consumption baskets contain many dissimilar items. In India, three CPI’s are constructed
(i) CPI for industrial workers.
(ii) CPI for urban non-manual employees.
(iii) CPI for agricultural labourers.
