Exploratory Data Analysis

Student-Teacher Ratios in NYC Public Schools

David White | Sunday, July 11, 2021

What is Exploratory Data Analysis?

Exploratory data analysis (EDA) is a technique used by data scientists to inspect, characterize and briefly summarize the contents of a dataset. EDA is often the first step when encountering a new or unfamiliar dataset. EDA helps the data scientist become acquainted with a dataset and test some basic assumptions about the data. By the end of the EDA process, some initial insights can be drawn from the dataset and a framework for further analysis or modeling is established.

This exploratory data analysis examines a dataset of information on public schools in the City of New York. The underlying data was released by the City of New York.
