Insider Knowledge

Terminology
Big DataBig Data

Both outsiders and insiders use 'Big Data' to describe extremely large datasets, but insiders comprehend its technical implications including storage, processing, and scalability challenges.

Data CleaningData Wrangling

Outsiders say 'Data Cleaning' to mean fixing data errors, but insiders use 'Data Wrangling' which indicates a broader process of transforming raw data into a usable format.

PredictionInference

Outsiders call it 'Prediction' but insiders distinguish 'Inference' for understanding relationships and causality beyond mere forecasting.

ErrorResidual

'Error' is a generic term for mistakes; insiders use 'Residual' to specifically describe the difference between observed and predicted values.

Computer ProgramScript

While outsiders say 'Computer Program' for any software, insiders use 'Script' for short, often single-purpose code files relevant to data tasks.

StatisticsStatistical Modeling

'Statistics' is known generally, but insiders emphasize 'Statistical Modeling' to denote building mathematical models to analyze data.

Data VisualizationViz

While 'Data Visualization' is formal, insiders use 'Viz' as shorthand to refer to the graphical representation of data.

Artificial IntelligenceAI

Outsiders often use the full term, while insiders prefer the acronym 'AI' which succinctly refers to systems capable of performing tasks requiring human intelligence.

Machine LearningML

Outsiders use 'Machine Learning' fully, insiders frequently use the abbreviation 'ML' in everyday communication.

Data AnalystData Scientist

Outsiders often conflate the two, but insiders differentiate 'Data Scientist' as a broader role involving modeling, programming, and strategic insight.

Inside Jokes

"Why did the Data Scientist break up with the Statistitian? Because they had too many biases!"

A pun on 'bias' from both a relationship context and its technical meaning in models, poking fun at the nuanced differences between these related professions.

"Trust me, I’m a Data Whisperer."

A humorous way data scientists describe their skill in teasing insights from messy or complex datasets, implying an almost magical intuition.
Facts & Sayings

Garbage In, Garbage Out (GIGO)

Highlights the principle that the quality of data input directly affects the quality of the output; if input data is flawed, results won't be trustworthy.

Feature Engineering is 80% of the Work

A humorous but true acknowledgment that preparing and selecting the right features is often the most time-consuming and critical part of data science projects.

Let the Data Speak

Emphasizes an analytical mindset of trusting data-driven insights over assumptions or personal bias.

Kaggle Gold

Refers to achieving a top performance or medal in Kaggle competitions, a badge of honor indicating high skill in predictive modeling and data problems.
Unwritten Rules

Always Attribute Your Data Sources

Crediting where data originated maintains trust and ethical standards, reflecting professionalism and respect for intellectual property.

Never Skip Exploratory Data Analysis (EDA)

Ignoring EDA is seen as a rookie mistake because it builds understanding essential for correct modeling choices.

Comment Your Code Clearly

Since data science projects are collaborative, clear documentation signals respect for teammates and future maintainers.

First Steps & Resources

Get-Started Steps
Time to basics: 3-5 weeks
1

Learn Python for Data Analysis

1 weekBasic
Summary: Start learning Python basics, focusing on data analysis libraries and syntax essentials.
Details: Python is the lingua franca of data science. Begin by installing Python and exploring its syntax, focusing on data types, loops, and functions. Next, familiarize yourself with essential libraries like pandas (for data manipulation), numpy (for numerical operations), and matplotlib (for basic plotting). Use interactive notebooks (like Jupyter) to practice hands-on. Beginners often struggle with installation and understanding library documentation—overcome this by following step-by-step beginner guides and using community Q&A forums for troubleshooting. This foundational step is crucial, as nearly all data science workflows rely on Python. Progress can be evaluated by your ability to load a dataset, perform simple manipulations (filtering, grouping), and create basic plots. Aim to complete small exercises, such as summarizing a CSV file or visualizing trends.
2

Explore Real-World Datasets

2-3 daysBasic
Summary: Download and explore open datasets, practicing data cleaning and basic exploratory analysis.
Details: Data scientists work with messy, real-world data. Find open datasets (such as those from government portals or public repositories) and practice loading them into Python. Focus on cleaning tasks: handling missing values, correcting data types, and removing duplicates. Use pandas for these operations. Beginners often underestimate the importance of data cleaning—avoid this by dedicating time to understand why data is messy and how to document your cleaning steps. Try to summarize the dataset: What variables are present? Are there outliers? This step builds your intuition for data quality and prepares you for more advanced analysis. Progress is measured by your ability to produce a clean, well-documented dataset and a short summary of its characteristics.
3

Study Basic Statistics Concepts

1 weekIntermediate
Summary: Review core statistics: mean, median, variance, correlation, and probability distributions.
Details: Statistical understanding is fundamental for data scientists. Refresh your knowledge of descriptive statistics (mean, median, mode, variance, standard deviation), probability basics, and common distributions (normal, binomial). Learn how to compute these using Python libraries. Many beginners skip statistics, but it’s essential for interpreting data and building models. Use visualizations to reinforce concepts—plot distributions and relationships between variables. If you struggle with math, start with intuitive explanations and gradually work through practical examples. Evaluate your progress by being able to explain what a correlation coefficient means, or by interpreting a histogram. This step ensures you can make sense of data before moving to modeling.
