It is a common practice to test data science aspirants on commonly used machine learning algorithms in interviews. These conventional algorithms being linear regression, logistic regression, clustering, decision trees etc. Data scientists are expected to possess an in-depth knowledge of these algorithms. We consulted hiring managers and data scientists from various organisations to know about the typical ML questions which they ask in an interview. Based on their extensive feedback a set of question and answers were prepared to help aspiring data scientists in their conversations.

From a marketing or statistical research to data analysis, linear regression model have an important role in the business. As the simple linear regression equation explains a correlation between 2 variables one independent and one dependent variable , it is a basis for many analyses and predictions. Apart from business and data-driven marketing , LR is used in many other areas such as analyzing data sets in statistics, biology or machine learning projects and etc. In our previous post linear regression models , we explained in details what is simple and multiple linear regression. Here, we concentrate on the examples of linear regression from the real life. You have to study the relationship between the monthly e-commerce sales and the online advertising costs.
