Study Notes

Data Analytics Overview

Data Analytics involves collecting and analyzing information to tell a story and convey insights clearly to various stakeholders.
It supports everyday decision-making on a larger scale, enabling complex choices based on data.
The process includes identifying a problem, forming a hypothesis, and testing it through data collection, cleaning, analysis, and presentation.

Key Analytics Types

Descriptive Analytics: Answers "What happened?"
Diagnostic Analytics: Explains "Why it happened?"
Predictive Analytics: Forecasts "What will happen next?"
Prescriptive Analytics: Suggests "What should be done next?"

Key Steps in Data Analysis

Understanding the Problem: Begin with a clear definition of the problem and desired outcomes.
Setting a Clear Metric: Establish measurable criteria (e.g., regional sales over a specific period).
Gathering Data: Identify necessary data sources and tools for analysis.
Cleaning Data: Resolve quality issues such as missing values and outliers for accuracy.
Analyzing and Mining Data: Explore cleaned data for patterns, trends, and correlations.
Interpreting Results: Evaluate findings while considering limitations and objections.
Presenting Findings: Communicate analyses effectively through reports, dashboards, and charts to support decision-making.

Perspectives on Data Analytics

Data analytics encompasses storytelling, whereby data is used to test hypotheses and clarify status efficiently.
It is fundamentally about problem-solving, where outcomes are supported by data-driven insights.
For financial professionals, it provides insights into a company’s financial status, informing predictions and strategic decisions.
It enhances communication and decision-making by sharing analyses that clarify business or data situations.

Modern Data Ecosystem

Consists of a complex network of interconnected elements, featuring diverse data formats and sources.
Involves an enterprise data environment for organizing and cleaning data.
Key roles include Data Engineers, Data Analysts, Data Scientists, Business Analysts, and Business Intelligence Analysts, all working towards deriving actionable insights.

Difference Between Data Analytics and Data Analysis

Data Analysis: Focuses on detailed examination to understand past performance, often irrespective of numbers.
Data Analytics: Involves systematic computational analysis of data for deriving insights and making predictions, primarily focusing on numerical manipulation.
The terms are used interchangeably within this course context, despite subtle differences in broader usage.
