You don’t need to master calculus to land your first data job.
A lot of beginners get stuck thinking they need to learn advanced statistics, machine learning, or complex math to get hired.
The reality is: YOU DON'T.
You can stand out with just basic math — if you know how to apply it.
If you're analyzing the salaries of 10 employees and: - 9 earn $50,000 - 1 earns $500,000
The average salary? $95,000. The median salary? $50,000.
Which one reflects reality better? I think you know the answer to that.
But why?! Because one extreme value skews the average — this is called positive skew. It's a positive skew because one very high salary is pulling the average up, even though most people earn much less.
This is why companies care about more than just averages. It's why analysts who understand context are more valuable than those who just know formulas.
If you know when to use averages vs. medians… If you understand skewness… If you can connect numbers to real-world decisions…
You're already ahead of 80% of the competition. You don’t need more math. You need more clarity.
