Is Synthetic Data Better Than Real Data? | Data Analysis

Key Highlights

  • Synthetic data offers privacy solutions while unlocking insights from data analysis.
  • The Synthetic Data Vault and DataCebo aim to revolutionize data generation and applications.

In 2012, a free online electronics course offered by edX attracted over 155,000 global participants, sparking a surge in online education popularity. EdX, a platform created by the Massachusetts Institute of Technology (MIT) and Harvard University, amassed a wealth of data about online education interactions, allowing researchers to explore factors affecting course completion and dropout rates.

To analyze this synthetic data, MIT data scientist Kalyan Veeramachaneni assigned 20 students but faced challenges due to data privacy constraints. The data was held on a secure, disconnected computer, making it cumbersome to access. This obstacle prompted the creation of synthetic students, computer-generated versions sharing real participants’ characteristics while preserving privacy.

Insights from Synthetic Data Analysis

Machine-learning algorithms were then applied to the synthetic students’ activities, revealing valuable insights into course completion predictors. These findings contributed to developing interventions to help real participants succeed in future courses.

Rise of Synthetic Data in Data Privacy

Veeramachaneni and his colleagues subsequently established the Synthetic Data Vault, an open-source software enabling users to model their data and generate alternative versions. This experience led them to co-found DataCebo in 2020, assisting other companies in leveraging synthetic data for analysis.

  • Privacy preservation drives synthetic data research, as artificial intelligence (AI) and machine learning utilize large data sets, raising concerns about privacy infringement.
  • AI algorithms require extensive data, compromising individuals’ privacy or potentially leading to discriminatory decision-making.

Promising Future of Data Generation TechnoloSynthetic Datagy

Synthetic data presents a promising solution, allowing computers to generate data closely resembling real information without compromising privacy. Beyond privacy, synthetic data addresses broader data set challenges. It offers a cost-effective, efficient way to add missing information and combat biases, making data sets more adaptable and controllable.

For researchers and data scientists, synthetic data represents a transformative approach to working with data, promoting flexibility and empowering data-driven applications and goals.


1. What is synthetic data?

Synthetic data is artificially generated data that mimics real data without containing real individuals’ private information.

2. Why is synthetic data important?

It preserves privacy in data analysis, addresses data limitations, and enables more ethical AI training.

3. Can synthetic data completely replace real data?

No, it’s meant to complement real data, not replace it, and its quality depends on the accuracy of the generation model.

4. What are potential applications for synthetic data?

Synthetic data can be used in medical research, AI development, simulations, and more where real data is limited or sensitive.
