Google Data Analytics Certificate


I recently completed the Google Data Analytics Professional Certificate on Coursera, and it was an eye-opening experience. In just a few months, I acquired essential skills, completed practical projects and obtained professional certification. This is a summary of the course of study faced in attaining a speciality in high demand in the job market as a data analyst.

What this professional certificate consists of

The Google Data Analytics Professional Certificate on Coursera is a comprehensive curriculum that can prepare anyone for a career in data analytics, even without experience or a degree. With eight courses, this program covers all aspects of data analysis, from collecting and cleaning data to creating visualizations, which can lead to decisions crucial to business success. The lecturers are Google employees with decades of experience in data analysis. This ensures quality learning with the help of the best professionals in the field.

What I learned

This program has enabled me to thoroughly understand the methodologies and processes used in the daily work of a junior or intermediate-level data analyst. I learned critical analytical skills, such as data cleaning, analysis and visualization, and the tools needed for optimal results, including spreadsheets, SQL, R programming and Tableau. I learned the best methodologies on how to clean and organize and complete data for analysis and the most critical computational functions to use in spreadsheets, SQL, and R programming; in addition, I learned how to visualize and present data results in dashboards, using the most commonly used visualization platforms.

How the learning process took place

The program includes more than 180 hours of lectures and hundreds of practice-based assessments, which helped me simulate real-world data analysis scenarios essential to perform profitably in the future workplace. The content is highly interactive and developed by Google employees with decades of experience in data analysis. Through videos, assessments, and hands-on workshops, I was introduced to analytical tools, platforms, and critical analytical skills needed for successful work. Skills acquired include data cleaning, problem-solving, critical thinking, ethics, and visualization. The platforms and tools I learned include spreadsheets, SQL, Tableau, and R programming.

The “Capstone Project” is the final course in the program, in which I had to complete a case study to share with potential employers to showcase my new skills. The capstone project was particularly challenging and required applying all the skills learned throughout the curriculum. I used actual data to complete a case study and presented the results in a concluding report.

Conclusions, my experience

Completing this program was not easy, but it was rewarding. Each course had its challenges, with the final act devoted to the “Capstone Project” particularly challenging, given that I had not previously used the R programming language. In particular, I was required to apply all the skills I had learned in previous courses and to work with an extensive data set to answer a series of questions. It was challenging, but completing it gave me great satisfaction and renewed confidence in my work abilities. Throughout the program, I learned skills in high demand in the job market, such as data cleaning, analysis and visualization. I also delved, through BigQuery, into the use of SQL, a programming language widely used in data analysis. These skills have opened up new career opportunities for me.

The entire route was taken to obtain certification:

Course 1: Foundations: Data, Data, Everywhere

Google Data Analytics: Foundations: Data, Data, Everywhere

In this introductory phase, I learned the basics of data analysis through a very hands-on and engaging learning program. I gained an understanding of the practices and processes used by data analysts and critical analytical skills and tools. The course also covers a range of terms and concepts relevant to the role of a junior data analyst and explores the role of analytics in the data ecosystem.

Course 2: Ask Questions to Make Data-Driven Decisions.

Google Data Analytics: Ask Questions to Make Data-Driven Decisions

In this course, we focus on how to ask practical questions to make data-driven decisions. I gained an understanding of data-driven decision-making, effective query techniques, and real-world business scenarios. The course also covers how and why spreadsheets are essential for data analysts, structured thinking and stakeholder management.

Course 3: Prepare Data for Exploration

Google Data Analytics: Prepare Data for Exploration

In this course, I was introduced to new topics to gain practical skills in data analysis. I learned to use spreadsheets and SQL to extract and use the correct data for their purposes and to organize and secure it. The course also covers how analysts decide what data to collect, structured and unstructured data, data types and formats, data validity, open data, data ethics, and privacy.

Course 4: Process Data from Dirty to Clean

Google Data Analytics: Process Data from Dirty to Clean

This course taught me techniques for verifying and cleaning data using spreadsheets and SQL, as well as how to verify the results of data cleaning and report on them. Topics covered include data integrity, data cleaning techniques with spreadsheets, basic SQL queries and functions, and data cleaning reports.

Course 5: Analyze Data to Answer Questions

Google Data Analytics: Analyze Data to Answer Questions

Based on the first four courses, we focus on the “analysis” phase of the data analysis process. I learned how to organize and format data using spreadsheets and SQL, aggregate data, and perform complex calculations on data. The course also covers using SQL formulas, functions, and queries to perform computational operations on data.

Course 6: Share Data Through the Art of Visualization.

Google Data Analytics: Share Data Through the Art of Visualization

In this course, I learned how to visualize and present data results using visualizations such as dashboards. Tableau, a data visualization platform for creating compelling visualizations for presentations, is used as the BI tool. The course also addresses the principles and practices needed to make effective presentations and how to consider potential limitations associated with data in presentations.

Course 7: Data Analysis with R Programming

Google Data Analytics: Data Analysis with R Programming

This course introduced me to the R programming language and how it can clean, organize, analyze, visualize, and report data in new and better-performing ways. Topics covered include the benefits of using R, RStudio, programming in R, R packages (including the Tidyverse package), data frames, generating visualizations in R, and documenting R programming using R Markdown.

Course 8: Google Data Analytics Capstone: Complete a Case Study

Google Data Analytics: Google Data Analytics Capstone: Complete a Case Study

In the concluding course, I had the opportunity to complete a case study to use in one’s portfolio to put oneself forward in the job market in data analysis. For the development of the Case Study, one is required to apply the methodology learned in the previous seven modules, thus with the selection of a scenario based on the analysis, drafting a set of questions, preparing, processing, analyzing, visualizing, and taking action performed on the scenario data used (Ask/Ask, Prepare/Prepare, Process/Process, Analyze/Analyze, Share/Share, Act/Act). The course also covers other helpful job search skills, such as actual job interviews and common questions, building an online portfolio, and more.
