  • Domain Professionals in Finance, Healthcare, and Operations: Working professionals who understand industry metrics and want to apply data-driven decision-making to risk analysis, patient outcomes, or supply chain efficiency.
  • Career Transitioners Without Prior Coding Experience: Non-technical beginners who are willing to practice consistently.

You do not need an advanced mathematics degree or prior software engineering experience to begin. Logical thinking and comfort with basic high-school arithmetic give you enough footing to start. Our trainers introduce Python for Data Science and foundational statistics from scratch so beginners build fluency step by step through daily lab exercises.


What Is Included in the Data Science Syllabus?

A strong Data Science course syllabus mirrors the actual lifecycle of an analytics project rather than treating tools in isolation. Across approximately 180 hours of practical lab work, learners progress through seven structured modules. (Note: Individual module-wise hour splits are provided in the detailed syllabus brochure upon request; only the total confirmed lab hours are listed here.)

Module 1: Python Programming

Python serves as the primary working language for data ingestion, automation, and modeling. Rather than stopping at basic syntax, learners practice writing clean and modular scripts that handle real operational data:

  • Environment Setup and Core Syntax: Installing Python environments, working in Jupyter Notebooks, and managing variables and data types along with operators.
  • Control Flow and Functions: Writing conditional statements, loops, reusable functions, and error-handling blocks so scripts do not crash when an unexpected input shows up.
  • Core Data Structures: Manipulating lists and tuples as well as sets and dictionaries to organize records efficiently.
  • File Handling and Object-Oriented Programming: Reading and writing external files and structuring reusable code modules using object-oriented programming principles where covered in the track.
  • Data Science Libraries Overview: Understanding how core analytical libraries sit on top of standard Python workflows.

Module 2: SQL and Database Management

Most enterprise data lives inside relational databases rather than standalone spreadsheets. When a SQL query returns duplicate rows because of an improper join, downstream reports and Machine Learning models break immediately. Learners master database querying using MySQL:

  • Database Fundamentals and SQL Commands: Understanding relational schemas and executing Data Definition Language (DDL) and Data Manipulation Language (DML) commands alongside Data Control Language (DCL) basics.
  • Filtering, Sorting, and Aggregations: Writing WHERE, GROUP BY, HAVING, and ORDER BY clauses with aggregate functions to summarize transactional tables accurately.
  • Joins and Subqueries: Combining multi-table records using inner, left, right, and self joins as well as nested subqueries without inflating row counts.

Module 3: Mathematics and Statistics

Algorithms rely on statistical assumptions that fail silently if you ignore data distributions. This module builds the quantitative reasoning needed to validate findings before trusting a model:

  • Descriptive Statistics: Measuring central tendency through mean, median, and mode while evaluating spread using variance and standard deviation.
  • Probability and Distributions: Working with conditional probability and core probability distributions to understand how real-world metrics behave.
  • Correlation, Regression, and Hypothesis Testing: Testing relationships between variables, interpreting p-values and confidence intervals, and avoiding false assumptions from noisy samples.

Module 4: Data Cleaning and Exploratory Data Analysis

Raw business extracts rarely arrive ready for modeling. CSV files often contain inconsistent date formats, mixed text encodings, duplicate entries, and missing values that skew predictions. Learners use Pandas and NumPy to audit and prepare datasets:

  • Numerical Computing with NumPy: Performing vectorized array operations and matrix transformations efficiently.
  • Data Manipulation with Pandas: Filtering DataFrames, merging tables, parsing dates, and reshaping messy extracts.
  • Data Preprocessing and Quality Checks: Detecting outliers, imputing or removing missing values systematically, encoding categorical variables, and scaling numerical features.
  • Exploratory Data Analysis (EDA): Uncovering patterns, anomalies, and variable relationships before choosing an algorithm.

Module 5: Machine Learning

Once data is clean, learners build, evaluate, and tune predictive models using Scikit-learn and related workflows. Special attention goes into diagnosing why a model performs well on training records yet fails on unseen test data:

  • Supervised Learning: Implementing linear and logistic regression along with classification algorithms such as Decision Trees, Random Forest, and Support Vector Machines (SVM).
  • Unsupervised Learning: Grouping unlabeled customer or operational records using clustering techniques.
  • Feature Engineering and Imbalanced Data: Creating informative input features and handling skewed target classes so classifiers do not simply predict the majority outcome.
  • Model Evaluation and Optimisation: Measuring performance using accuracy, precision, recall, F1-score, and error metrics while tuning hyperparameters to prevent overfitting.

Module 6: Generative AI and LLM Fundamentals

Modern analytics workflows increasingly pair classical predictive models with Generative AI tools for unstructured text processing and faster exploratory analysis. This module introduces practical AI integration:

  • Generative AI and LLM Concepts: Understanding how Large Language Models (LLMs) process text tokens and generate structured responses.
  • Prompt Engineering: Designing clear, repeatable prompts for data summarization, code explanation, and schema extraction.
  • AI-Assisted Data Workflows: Applying Generative AI responsibly to accelerate documentation, text classification, and analytical prototyping while verifying outputs for accuracy.

Module 7: Data Visualisation and Business Intelligence

Even the sharpest predictive model loses value if decision-makers misread the dashboard. For example, an improperly configured aggregation in Power BI can display misleading totals across filtered categories. Learners build clear, accurate executive reports:

  • Python Visualisation Libraries: Plotting distributions, trend lines, and correlation heatmaps using Matplotlib and Seaborn.
  • Power BI and Power Query: Connecting data sources, cleaning tables in Power Query, writing DAX measures where included, and designing interactive business dashboards.
  • Tableau and Data Storytelling: Building visual views in Tableau and structuring clear analytical narratives that highlight actionable business takeaways.


Which Projects Will You Build During Training?

Employers reviewing resumes for Data Science classes for beginners and career switchers look closely at what you have actually built and debugged. Completing guided, real-world projects proves you can handle ambiguous data rather than simply following tutorial notebooks.

During training at SevenMentor, learners work on practical projects drawn from real analytical problem statements—such as:

  • Fake News Detection: Applies Natural Language Processing (NLP) techniques including tokenization, stopword removal, stemming, and TF-IDF vectorization alongside classification models such as Logistic Regression, Random Forest, SVM, and deep learning or transformer architectures to separate reliable articles from fabricated news.
  • Sales Forecasting Using Time Series Analysis: Introduces historical trend decomposition, seasonality checks, and predictive time-series modeling to estimate future product demand.
  • Resume Screening System: Demonstrates automated text preprocessing and document classification to match candidate profiles against role requirements.
  • Disease Prediction Using Patient Symptoms: Uses structured clinical feature engineering and supervised classification algorithms to evaluate symptom patterns and predict health conditions.
  • Music Genre Classification: Explores multi-class classification using extracted audio and numerical features to categorize tracks accurately.

Not every learner completes every project independently; trainers guide cohorts through selected projects and a comprehensive capstone project that ties together raw data collection, preprocessing, exploratory analysis, model training, validation metrics, and final presentation.
