How To Use ChatGPT: Data Analyst & Data Scientist Use Cases

You’ve likely heard the buzz about AI tools like ChatGPT and Google Bard.

After all, ChatGPT took the world by storm in late 2022, becoming the fastest product of all-time to reach one million users… in just 5 days!

While it’s clear these chat-based Large Language Model (LLM) tools are popular, it might not be as obvious how you can apply them in your workflow as an Analytics pro. That’s what we’ll be talking about today.

Why Data Pros Need To Learn To Use AI Tools

The world is changing, fast.

Tools like ChatGPT and Google Bard are changing the game, allowing users to complete tasks in minutes that used to take hours.

Here are just some of the reasons any data pro should consider using AI:

  • Improve your performance & efficiency
  • Automate routine, low-value tasks
  • Spend more time on the higher value activities
  • Use AI as an easy way to check your work
  • Leverage AI tools to learn and get questions answered quickly
  • Stay on the cutting edge and competitive in your field

Will AI Tools Replace The Need For Data Analyst And Data Scientist Jobs?

This question gets a lot of people pretty fired up… especially folks in these roles or studying to enter the field. Makes sense, it’s a scary concept.

But fears of Analytics pros losing their jobs to AI are totally overblown.

Companies will always need the special sauce that truly great Analysts bring to the table:

  • Strategic thinking / problem solving
  • Communication skills
  • Technical proficiency

AI tools can help with the technical gaps, but when it comes to thinking strategically about a business, deciding where to focus, advocating for and driving change within an organization, AI isn’t showing much promise.

For the foreseeable future, any solid Analyst with good strategic thinking, problem solving, and communication skills is probably safe from AI taking their job.

While AI likely won’t take your job, another Analyst who uses AI might.

Imagine trying to be an Analyst today, and never having learned how to use spreadsheets or the internet. You’d be at such a disadvantage relative to your competition. We’ll be saying the same thing about AI tools very soon.

To make sure you continue to be seen as a top talent in data, you’ll need to work on the uniquely human skills, build a solid technical foundation, and learn to use cutting edge technology like AI. If you can do that, you’ll be truly unstoppable in your career.

Warning: Common Pitfalls of Using LLM Tools

Before we get into specific analytics use case for AI, it’s worth noting some of the things you need to watch out for while you’re using them.

  • Don’t get yourself in trouble by sharing sensitive company data. Your information isn’t private once you share it with an LLM. A number of companies have already banned employees from using these tools. Any employer would be upset if they found out you compromised sensitive information externally. Don’t get yourself fired.
  • LLMs are known to “hallucinate”. This is a nice term for saying they make stuff up. They do it all the time. The problem is, these tools sound just as confident when hallucinating as when they are giving you accurate information.
  • Sometimes you’ll get an answer to your question, but the solution you receive might not be the optimal one.
  • Today’s LLM tools are very broad and they might lack specific domain expertise or deep knowledge of a specific area where you need them to perform.
  • LLMs are NOT capable of common sense, and cannot (at least today) replicate human judgment. These models are trained on the open internet. A lot of the information out there is bad, and the models aren’t good at making that distinction.

The general rules of thumb here are to use sound judgment about what you should and shouldn’t be doing with these tools, and think critically about the responses you’re getting back.

If you can do that, and remain aware of the current limitations of LLMs, then they can be really valuable tools that will help you speed things up and automate some of the more mundane tasks in the analytics workflow.

It’s also important to note that these tools are improving very fast. Many of the limitations we are discussing today are problems that may be solved in the near future. Keep these pitfalls in mind, but considering everything related to AI tools a moving target.

Best Practices For Using AI Tools For Analytics

One of the quickest ways to be more effective with these tools is to learn how to write better prompts.

Here are some of our Prompt Engineering tips to help you get the most out of LLMs like ChatGPT and Google Bard:

  1. Be clear and specific. The more detailed information you give the AI, the more likely you are to get a high value response.

2. Provide context. The more information you can share about your situation and the problem you are trying to solve, the better.

3. Establish roles. Telling the AI tool who it should impersonate, and who the response is for can go a long way toward shaping a relevant response.

4. Set the tone. Try prescribing things like how technical, how detailed, how formal, and how long you want the response to be.

These are good rules of thumb, but don’t overthink them at the expense of speed. It’s easy to scrap your conversation and start fresh if you don’t like where things are headed. So aim for good progress here and don’t worry about perfection when it comes to prompt writing.
