Although the questions are set in such a way that the difficulty level of each shift remains the same but still there might be a possibility that difficulty level of shift varies. In different shifts, the question paper set is different. So they can’t examine all candidates at the same time, therefore the exam is conducted in shifts or even on different days. In CAT (an aptitude test conducted by IIM’s for the selection in top B-schools in India)too many applications are received. It’s too complicated, isn’t it? Let’s take an example and clear this out. In this case, both numerator and denominator will be equal and cancel each other to give us the value of Xnew =1. Since numerator will become Xmin –Xmin, which is nothing but 0.
Here, Xmax and Xmin are the maximum and minimum values of the feature respectively. The formula for calculating normalized score: It is a scaling technique method in which data points are shifted and rescaled so that they end up in a range of 0 to 1. So bear with me for five minutes it will be worth your time. Their application in real life using examples, and the difference between them. In this article, I’ll explain what normalization and standardization are in a simple language as possible without using much of technical jargon. And that’s where the interviewer takes the step and boom! you are doomed. But there is a subtle difference between these two. People usually get confused between these two terms.
The term normalization and standardization are used a lot in statistics and data science.
