Exploratory Data Analysis (EDA) represents the initial step in a Machine Learning Project. In Data Science, EDA involves analyzing data to identify their primary characteristics and information.

EDA often utilizes Data Visualization techniques to summarize dataset information and employs basic or more complex statistical measures such as mean, median, standard deviation, or data distribution.

When dealing with Text Data, the foundational approach remains similar, yet the tools employed may differ.

Consider a dataset with columns for Hotel Review and Rating. Can we employ the standard EDA approach here? Yes, but it might result in a limited analysis. For instance, describing the Rating variable using mean and median might not provide substantial insights. With text data, our focus shifts to other tools such as word counting, word frequency, and bigrams.

Let’s delve into the Exploratory Data Analysis of Text Data.
