Data Analytics Introduction


What is data analytics? Here is what Wikipedia says about data analysis: “Data analysis is a process of inspecting, cleansing, transforming, and modeling data with the goal of discovering useful information, informing conclusions, and supporting decision-making. Data analysis has multiple facets and approaches, encompassing diverse techniques under a variety of names, and is used in different business, science, and social science domains. In today’s business world, data analysis plays a role in making decisions more scientific and helping businesses operate more effectively”.

Data analytics is about using data to make better decisions. Data analytics is the science of data. Data analytics is a broad concept that encompasses managing and using data to the tools and methods data workers use. It involves managing the RDBMS and sandboxes along with the prograaming tools like Python and R. Regarding data, data analysis, and the data ecosystem, note that all of these things fit under the data analytics umbrella.

Data Analysis is part of the world of Data Science.

Data analysis is the collection, transformation, and organization of data to draw conclusions, make predictions, and drive informed decision-making. To understand the process a bit better, consider the Data Analytics Life Cycle.

Ken Jee

Ken Jee’s channel says “Hi, I’m Ken! Data Science, machine learning, AI and Sports Analytics are my passions. When I was first starting out on my data science journey I was extremely lost. There were very few resources for me to learn about this field from. I decided to start making YouTube videos to share my experiences and to help others learn about data science, machine learning, and AI.” Ken is a data scientist, not a data analyst, but he makes my list anyway.

Certificates

There are two Data Analytics certificates available. One is from Google and one is from IBM. Here are two YouTube videos that discuss and compare them. What’s the best certificate for data analysts? Google vs IBM Data Analyst Certificate by Tina Huang. It’s 15 minutes long. Here is another video called Google vs IBM Data Analytics Certificates | Which is Better?. It’s about 6 minutes long. Here’s one by Luke called Become a DATA ANALYST with NO degree?!? The Google Data Analytics Professional Certificate. It’s 11 and a half minutes long.

The Google Data Analytics Professional Certificate Coursera is over 180 hours of coursework and should take 3 to 5 months to complete if you are doing 10 to 20 hours per week. You learn Google Sheets, SQL in Big Query (Google Cloud), Tableau (for visualization), R Language in RStudio. Google focuses more on resume and portfolio preparation than IBM. They style of content delivery is video and talking heads, where at IBM it’s animation (slides) and narration. Once you finish, Google will share your profile with potential employers.

The IBM Data Analyst with Excel and R Professional Certificate at Coursera is about 140 hours of coursework that typically takes 3 to 4 months to complete if you are doing around 10 to 15 hours a week. You learn Excel, Cognos, SQL, Dashboards, IBM Cloud, and Python taught in Jupiter Notebooks. It’s heavy on Python. Many people prefer Python over R, (or vice versa) but what you could do is take a certification and then add a Course to the end of it. Alex the Analyst recommends the Google certification with a Python couse along with it. Why? Alex prefers the style of delivery and the focus on resumes, interviews, and your portfolio.
