In this module, you’ll apply key data collection and analysis techniques using APIs and web scraping. You’ll start by exploring HTTP requests and using APIs to retrieve and paginate job postings across different technologies. Then, you’ll work with a JSON endpoint to collect job data through API requests. Next, you’ll use web scraping techniques to download webpages, extract links and images, and gather data from HTML tables into a CSV file. By the end of this module, you’ll have hands-on experience with real-world data collection methods. You’ll also complete a graded quiz to check your understanding.

In this module, you will perform essential data-wrangling techniques necessary for cleaning and preparing datasets for analysis. Throughout the module, you will engage in hands-on activities to identify and handle common data issues, including duplicate entries and missing values. You will strategically remove duplicate records, apply suitable imputation strategies for missing data, and normalize datasets to ensure consistency and accuracy. Additionally, you will have a graded quizz to assess your understanding and reinforce the concepts covered.

In this module, you will engage in essential exploratory data analysis (EDA) techniques to uncover meaningful insights from your data set. You will start by identifying the distribution of the data through plotting distribution curves and histograms, which are crucial for understanding how values are spread across different features. Next, you will detect outliers that may skew your analysis and learn how to effectively remove them to ensure data integrity. Additionally, you will explore correlations between various features in the data set, revealing relationships that can inform your overall analysis. Finally, you will create a new DataFrame to organize and present your findings. The module includes a graded quiz to test your knowledge.

In this lab, you will perform essential data visualization techniques to extract meaningful insights from the Stack Overflow survey data set. You will start by visualizing the distribution of data using histograms and box plots to understand the spread of compensation and age. Next, you will explore relationships between features through scatterplots and bubble plots, followed by examining the composition of data with pie charts and stacked charts. Additionally, you will compare data across categories using line and bar charts. The module includes a graded quizz that will assess your knowledge of these concepts, ensuring you are well prepared for further analysis in your final project.

In this module, you will create dashboards using Stack Overflow survey data using either IBM Cognos Analytics or Google Looker Studio. The assignment is divided into Part A: Building a Dashboard with IBM Cognos Analytics and Part B: Building a Dashboard with Google Looker Studio. You will design a dashboard with sections on Current Technology Usage, Future Technology Trends, and Demographics. After completing the assignment, you will be required to submit the link of the Cognos or Looker Studio dashboard you complete. The module also includes a checklist that helps you ensure you have completed all necessary tasks before moving on.

In the final module, you will focus on presenting your data findings effectively. You will begin by exploring key elements contributing to a successful data findings report, including structuring your report, using best practices for data visualization, and presenting complex information in an engaging, accessible format. The module also includes labs covering basics in PowerPoint, foundational presentation techniques, and saving your presentation as a PDF to ensure a polished, professional final product. Finally, you will complete and submit a final presentation highlighting insights derived from the Stack Overflow Developer Survey data for evaluation through AI Grading or Peer Review.
