Becoming an AI data scientist has levels to it.

Here's a complete roadmap: Image
Becoming an AI data scientist is a journey with multiple levels, each requiring specific tools and skills.

I’ve outlined a progression of levels with relevant skills and tools:
Level 1: Foundations of Data Science

- Python: Core programming language for data science (e.g., variables, loops, functions).
- Pandas: Data manipulation and analysis (e.g., DataFrames, cleaning data).
- NumPy: Numerical computations (e.g., arrays, linear algebra basics).
-Plotly: Data visualization (e.g., plotting charts, exploring trends).
- SQL: Querying databases for data extraction.Image

Understanding P-Values is essential for improving regression models.

In 2 minutes, I'll crush your confusion.

Let's go: Image
1. The p-value:

A p-value in statistics is a measure used to assess the strength of the evidence against a null hypothesis. Image
2. Null Hypothesis (H₀):

The null hypothesis is the default position that there is no relationship between two measured phenomena or no association among groups. For example, under H₀, the regressor does not affect the outcome. Image

Data scientists are out.

The Generative AI Data Scientist is in.

Let me explain: Image
Companies are sitting on mountains of unstructured data.

PDF
Word docs
Meeting notes
Emails
Videos
Audio Transcripts

This is useful data. But it's unusable in its existing form. Image
The AI data scientist builds the systems to analyze information, gain business insights, and automates the process.

- Models the system
- Use AI to extract insights
- Drives predictive business insights

Correlation is the skill that has singlehandedly benefitted me the most in my career.

In 3 minutes I'll demolish your confusion (and share strengths and weaknesses you might be missing).

Let's go: Image
1. Correlation:

Correlation is a statistical measure that describes the extent to which two variables change together. It can indicate whether and how strongly pairs of variables are related. Image
2. Types of correlation:

Several types of correlation are used in statistics to measure the strength and direction of the relationship between variables. The three most common types are Pearson, Spearman Rank, and Kendall's Tau. We'll focus on Pearson since that is what I use 95% of the time.Image

Data Science for Business.

The book that helped me connect the dots. Let's dive in: Image
1. CRISP Data Mining Process

The foundation for applying data science to business is the CRISP method.

This is a helpful framework for integrating data science with the business understanding. Image
2. Machine Learning Predictions as Probabilities

One of the most important part of machine learning is probability.

We can estimate the probability from machine learning predictions.

Once you get this, the next framework opens up: Image

90% of data scientists can improve their SQL for business intelligence.

In 3 minutes, learn the 20% of SQL gets 80% of results: Image
🔍 SELECT Basics:

Start with SELECT * FROM table to retrieve all rows & columns.

Remember, SQL isn’t case-sensitive—but capitalizing keywords (SELECT, FROM) makes your queries easier to read. Image
📝 Choosing Specific Fields:

Instead of the star (*), list only the fields you need (e.g., field1, field2) and rename them using AS for clarity.

Clear queries lead to clear insights. Image
