If you're starting out in data science (or if your wondering what you need to learn), don't believe everything you read. 🧵

Spot BS and focus on these 4 steps to grow your career.

My friend Rafael Nicolas Fermin Cota (Nico) pointed me to this modified graphic from a Harvard Business Review Article on "Prioritizing Which Data Science Skills Your Company Needs".

With ChatGPT, AI, and the "trendiness" of buzzwords, this graphic becomes even more dangerous. hbr.org/2018/10/priori…

You hear "Harvard Business Review", and you think this must be 100% accurate.

Well, they dropped the ball in my opinion.

So if you're coming up with an educational plan in 2023:

1. Focus on #Stats

This is the precursor to everything & will help you tremendously

In #R: learn the stats package.

I use:
lm(),
cor(),
math operations like mean(), sum(), sd(), IQR()
length() for counts

2. Learn how to work with #Data

Data cleaning and transformation is 90% of what you will do.

In #R: learn the #dplyr and #tidyr packages.

I use:
group_by(),
summarise(),
mutate(),
count(),
distinct(),
pivot_wider(), pivot_longer(),
nest() and unnest().

3. Build skills in #DataVisualization

Most ML specialists can't do this. It's a crime.

Data Visualization is the heart of understanding.

For Data Viz, Learn #ggplot2 & #plotly.

In R Iuse:
ggplot() and aes(),
geom_line() for line plots,
geom_col() for bar plots,
geom_point() for scatter plots, and
geom_smooth() for smoothers

4. Skip over the #buzzwords until after you've learned the foundations

#AI, #DataScience, #MachineLearning are useless without a clear understanding of how to use them inside of your data analysis workflow.

And if you are interested in becoming a 6-figure data scientist in 2023 (& feel as lost as I did), then I can help.

I have a free workshop on May 17th where I will explain the shift that's going on in data science & how to become a 6-figure data scientist in 2023.

Seriously. This workshop is insane. I've packaged 6 years' worth of tools and tactics that my students are using to land awesome jobs:

- Promotion to Senior Director of Analytics ($175K+)
- Data Scientist at Verizon (125K+)
- R Shiny Developer at CVS Health ($125K+)

- Data Scientist at CitiBank (100K Base + Bonus)
- Senior Data Scientist at Bank of Canada ($125K+)
- And more $100K+ jobs

I'll explain everything in my free workshop.

What's Your Next Step?

Join me and 1,000+ future data scientists as we learn how to earn 6-figures even in a recession.
