You don’t need a PhD in stats. Focus on:

• Descriptive stats (mean, median, std dev)

• Probability basics

• Distributions (normal, binomial)

• Hypothesis testing

• Correlation vs causation

• Regression (linear + logistic)

That’s enough to get started. Pair it with Excel, SQL, and some Python. Happy to help if you’ve got more specific questions.

You don’t need deep academic stats, just practical stats that help you make decisions with data. Focus on why something is used, not just how.

Focus on these concepts

• Averages & Spread (mean, median, mode, standard deviation) → For summarizing data

• Trends & Relationships (correlation, simple regression) → To find patterns

• Distributions (normal, skewed, uniform) → To understand data behavior

• Basic Probability → For handling uncertainty

• Sampling & Bias → So your data insights are valid

• Hypothesis Testing (p-values, t-tests) → To compare groups or test assumptions

Advice So You Don’t Burn Out:

• Learn one thing at a time — stats first, then tools like Excel/SQL/Python

• Practice with real datasets, even silly ones (e.g., Netflix ratings or Pokémon stats)

• Don’t obsess over perfect learning paths — progress matters more

• Ask for guidance — many mentors are happy to help if you’re curious and consistent

Start small, stay consistent. You don’t need to master everything — just learn enough to ask good questions and trust your data.

You need a strong foundational understanding of applied statistics, not a PhD-level deep dive. Here are the core topics you should master:

Descriptive Statistics 
Topics – Mean, Median, Mode, Range, Variance, Standard Deviation
Why – Helps summarize and understand data distributions

Probability
Topics – Basic probability, combinations/permutations, conditional probability, Bayes’ Theorem (intro only)
Why – Useful in predicting outcomes and understanding uncertainty

Distributions
Topics – Normal, Binomial, Poisson
Why – Essential for making assumptions and running models

Inferential Statistics
Topics – Hypothesis testing, confidence intervals, p-values, z-test, t-test
Why – Helps make conclusions about populations from samples

Correlation & Regression
Topics – Correlation, linear regression, multivariate regression
Why – Essential for discovering relationships and predictions

Data Sampling
Topics – Types of sampling, bias, sample size, central limit theorem
Why – Important for data collection and validity of results

ANOVA & Chi-Square
Topics – Basics of ANOVA and chi-square test
Why – Useful for comparing groups or categories

Learning Strategy (So You Don’t Feel Overwhelmed)
-Start with structured courses — e.g., Google Data Analytics, IBM Data Analyst, or Udemy/LinkedIn courses.

-Apply what you learn — Use free datasets (like on Kaggle) and build small projects.

-Stick to one concept at a time — Don’t try to learn Python, SQL, and stats all at once.

-Join communities — Reddit, Discord, and LinkedIn groups for data analytics are great for help and mentorship.
