Data Analytics Overview

Data analytics extracts trends and patterns from raw data to aid decision-making, optimize operations, and enhance business management.
It is crucial for scientific decision-making and improving resource utilization.
Traditional accounting methods, like notebooks and Excel, pose challenges in tracking cash flow for small and medium businesses (SMBs) and startups.

Challenges in Traditional Accounting

Small expenses, such as taxes, are often difficult to track and manage.
Limited resources often require business owners to handle multiple roles, including HR and payroll.
Traditional methods lead to complex financial reports, inadequate insights, and reliance on Excel tools.

Data Analytics Impact on Accounting

Uncovers critical insights and identifies improvements in financial processes.
Enhances risk management capabilities and supports better decision-making.

Application of Data Analytics by Accountants

Tax accountants and auditors use continuous data monitoring for accuracy and error reduction.
Data analytics enables quicker investment and tax decision-making.

Phases of the Data Analysis Process

Data Requirements Specification: Determine data needed based on specific questions or experiments.
Data Collection: Gather accurate information to ensure valid decision-making.
Data Processing: Organize and prepare data for analysis.
Data Cleaning: Correct errors and inconsistencies in the data.
Data Analysis: Apply various techniques to interpret and analyze cleaned data.

Key Terminologies in Data Analytics

Observation: A single record of data, also known as a case or row.
Data Sampling: Technique for analyzing a representative subset of data.
Dataset: A collection of data relevant to specific use cases, including records like medical or loan approvals.
Prediction: Assessment of future outcomes based on historical data.

Types of Data

Structured Data: Fixed-format data, e.g., employee details.
Unstructured Data: Lacks specific structure, e.g., emails, making up about 80% of business data.
Semi-Structured Data: Contains elements of both structured and unstructured data, e.g., JSON files.

Analyzing Unstructured Data

Unstructured data primarily serves Business Intelligence (BI) and analytics purposes rather than transactional applications.
Common uses include sentiment analysis, targeted marketing, and customer relationship management.

Qualitative and Quantitative Data

Qualitative Data: Classifications based on attributes, essential in various statistical analyses.
Quantitative Data: Includes measurements and numerical analyses relevant in statistics.

Basic Statistical Parameters

Mean: Average of data points, calculated by summing values and dividing by the quantity.
Variance: Measures data distribution relative to the mean.
Standard Deviation: Indicates data variability from the mean.

SMART Questions for Effective Queries

Craft questions that are Specific, Measurable, Action-oriented, Relevant, and Time-bound.
Avoid leading, closed-ended, or vague questions.

Data Cleansing and Management

Data cleansing resolves corrupt, inaccurate, or irrelevant data to enhance data reliability and consistency.
Data scrubbing focuses on eliminating duplicate or outdated data.
Clean data is essential for effective decision-making within data-driven business environments.
