Обзор тематических направлений образовательных материалов
Ниже представлен обзор направлений в изучении основ работы с данными. Информация носит описательный характер.
Statistics, the Basics
Mean, median, spread, correlation. Explained on intuition, without dragging you through the formulas.
Think of it as a vocabulary layer - enough to follow a conversation, not to run a study.
Getting Data Ready
Raw data is messy. These pages walk through why cleanup matters and the usual order of steps - checking, filtering, reshaping - before anything else happens.
Format is descriptive. You get the logic of the process, not a click-by-click drill.
Charts and Visuals
Bars, lines, scatter, the odd heatmap. Materials cover which chart fits which question, and the small choices - axis, scale, color - that keep a picture honest.
Delivered as reading notes with worked examples pointed out along the way.
Data Fundamentals
Start here. What counts as data, where it comes from, and the rough shapes it takes - tables, records, timestamps, categories.
Read as: short primers with plain-language notes, no exercises attached.
