Hypothesis testing helps us to validate the various claims made by different people in different scenario. For example if we claim that there is no significant difference between boys and girls intelligence level. So can we validate it significantly? Or can we validate that smoking causes cancer?
Data Analyst job is to explore the data, interpret it and finally convert it to information. This information will then help decision makers to take business related decisions. As a Data Analyst your roles and responsibilities includes starting from data collection, interpretation, visualization, dashboard building and finally story telling around the information derived from data.
Let me start with simple question. Can we compare Mango and Apple? Both have different features in terms of tastes, sweetness, health benefits etc. So comparison can be performed between similar entities else it will be biased. Same logic applies to Machine Learning as well. Feature Scaling in Machine Learning brings features to the same scale before we apply any comparison or model building. Normalization and Standardization are the two frequently used techniques of Feature Scaling in Machine Learning.
