Project-based learning is an effective approach for mastering data science concepts. Data Science is a multi-disciplinary field that requires a good understanding of mathematics, statistics and probability, and programming. For individuals who already have some background in mathematics and programming, the transition to data science can be seamless if the project-based learning approach is implemented.
In project-based learning, you learn by working on hands-on data science projects. To illustrate the project-based learning approach, let us assume the project is to build a machine learning algorithm for classifying a binary target variable. We will assume that the programming language used for executing the project is python.
To import your data, you need to learn how to use the pandas library. There are lots of resources online that will teach you about the pandas library. With pandas, you can import and display your dataset into your work space. This ensures that the dataset used is the correct dataset for the project.
During the data preprocessing stage, you will learn how to preprocess your data. For example, how to deal with missing values and other imperfections in the dataset. Then you also want to scale your data using methods such as standardization or normalization. You can also encode the target class so that the binary target variable takes on numerical values such as 0 or 1.
