Introduction Exploratory Data Analysis (EDA) is a critical first step in understanding any dataset before modeling or drawing insights. This analysis focuses on a car insurance dataset. Key attributes such as car manufacturer, engine size, number of cylinders, and performance metrics are analysed to uncover patterns and relationships that influence insurance risk. Through systematic data…
Introduction In the world of data science and analytics, the quality of your analysis is only as good as the quality of your data. Unfortunately, real-world datasets are often messy, requiring extensive cleaning before you can extract meaningful insights. In this tutorial, we’ll walk through a step-by-step process to clean a typical messy IMDB dataset…
Introduction Data cleaning is a crucial step in the data analysis process, especially when dealing with real-world datasets, which are often incomplete, inconsistent, and filled with errors. In this tutorial, we’ll walk through the process of cleaning-up a ‘messy’ healthcare dataset using Python. This guide will be helpful for data analysts, data scientists, or anyone…
Introduction Dealing with messy datasets is a common challenge when working with real-world data as a Data Scientist or Data Analyst. In this exercise, we’ll walk through the process of cleaning a typical messy Human Resources (HR) dataset using Python programming.
Introduction When working with real-world data, it’s common to encounter datasets that are messy, inconsistent, and full of missing values. Before diving into any analysis, it’s crucial to clean your data to ensure accuracy and reliability. In this tutorial, we’ll be working with a dataset that contains job postings for data science positions. The data…
Introduction Dealing with messy data is a common challenge in data analysis and can significantly impact the results of your analysis. Cleaning the data is the first and most crucial step toward obtaining reliable insights. The dataset we will use in this tutorial contains information about a warehouse inventory, but it is plagued with issues…
