  • Regression Analysis: Modeling relationships between variables to make predictions.
  • Experimental Design: Planning experiments to collect data efficiently and answer specific research questions.

Computer Science Principles

Data scientists need solid programming skills and an acquaintance with computer science concepts. Curriculum Overview: What to Expect in a Data Science Bachelor's Degree Programs often features these courses:

  • Programming Fundamentals: Introduces programming concepts using languages such as Python or R, which are used in data analysis and machine learning.
  • Data Structures and Algorithms: Covers methods for organizing and manipulating data, including lists, trees, graphs, and sorting/searching algorithms.
  • Database Management: Introduces relational databases (SQL) and NoSQL databases, along with query languages and database design principles.
  • Cloud Computing: Learning to use cloud platforms for data storage and processing, such as Amazon Web Services (AWS), Google Cloud Platform (GCP), or Microsoft Azure.

Data Wrangling and Visualization

Data rarely comes in a neat, ready-to-analyze format. You'll learn how to:

  • Data Cleaning: Techniques for handling missing values, outliers, and inconsistencies in datasets.
  • Data Transformation: Scaling, normalization, and other methods to prepare data for analysis.
  • Data Visualization: Creating effective charts and graphs to explore data and communicate findings using tools like Matplotlib, Seaborn, or Tableau.

Advanced Topics and Specializations

After covering the core curriculum, many programs offer advanced courses and opportunities for specialization. Curriculum Overview: What to Expect in a Data Science Bachelor's Degree Programs will usually include some of these advanced specializations as options.

Machine Learning

This area is at the forefront of data science. Expect courses on:

  • Unsupervised Learning: Discovering patterns in unlabeled data using techniques like clustering and dimensionality reduction.
  • Deep Learning: Neural networks with multiple layers, used for image recognition, natural language processing, and other complex tasks. (TensorFlow and PyTorch are popular frameworks.)
  • Reinforcement Learning: Training agents to make decisions in an environment to maximize a reward.

Big Data Technologies

Handling large datasets requires specialized tools and techniques. Expect exposure to:

  • Hadoop: A framework for distributed storage and processing of big data.
  • Spark: A fast, in-memory data processing engine.
  • NoSQL Databases: Alternatives to relational databases designed for handling large volumes of unstructured data.

Data Mining

Data mining discovers patterns, trends, and knowledge from large datasets. Topics can include:

  • Association Rule Mining: Discovering relationships between variables in large datasets.
  • Classification: Building models to categorize data into predefined classes.
  • Clustering: Grouping similar data points together based on their characteristics.

Natural Language Processing (NLP)

NLP enables computers to understand and process human language. Courses may cover:

  • Text Mining: Extracting information from text documents.
  • Sentiment Analysis: Determining the emotional tone of text.
  • Machine Translation: Automatically translating text from one language to another.
