Preeti Manchanda
Educational research and data analyst
I turn complex data into clear insights that help people make better decisions.
Noida, IndiaA little about me
About me
The person behind the data
I bring a researcher’s curiosity and an analyst’s attention to detail.
I’m an educational researcher and data analyst with more than six years of experience in experimental design, assessment analytics, and large-scale survey research.
My work has ranged from understanding how children learn to validating talent assessments. Across each project, I combine rigorous statistical methods with a human-centred perspective because data matters most when it helps us better understand people.
With advanced R skills and experience across education, health, and social research, I turn complex data into clear, credible evidence that supports better decisions.
