After preparing the dataset for analysis and conducting a basic analysis using Microsoft Excel, it is time to move to a more sophisticated territory. In this module, you will be loading your cleaned and prepared data to the PostgreSQL server and writing SQL queries using pgAdmin to perform advanced data manipulation to filter and sort the data and calculate aggregates. You’ll also perform a multidimensional analysis using cubes and rollups to observe trends and summarize data along hierarchies.

Data visualization refers to insights through visually compelling reports and dashboards. In this module, you’ll use Microsoft Excel to create basic charts like line and bar charts and advanced charts like sunbursts and scatterplots to visualize trends and gain insights. Further, you’ll conduct a statistical analysis of the data using regression techniques to predict outcomes.

Tools like Tableau provide advanced visualization capabilities. They allow you to extract more information from the data by providing better sorting and filtering features. They help you create interactive dashboards that enable users to make better decisions. In this module, you’ll be performing advanced data visualization tasks. You’ll create worksheets using advanced filters and emphasizers and then assemble multiple worksheets to create interactive dashboards having features like calculated fields and interactivity allowing the filtering of data across multiple views.

In this module, you’ll be presenting your findings. You’ll be creating a PowerPoint presentation telling a compelling story of your analysis. You’ll be asked to include screenshots from tasks performed throughout the course and links to dashboards as proof of completion. Before you begin, you may go through the videos and labs providing guidance on how to present your findings and how to use PowerPoint. The presentation will be uploaded in a PDF format and will be reviewed by your peers. You’ll also be reviewing the work of some of your peers.

In this bonus module, you will gain valuable insights and skills to excel in your job search for BI Analyst positions. You will evaluate effective job search strategies tailored to the BI analysis field. You will create a resume and develop an effective portfolio. You’ll build a professional online presence and use networking techniques to help you access hidden job opportunities.
