How to Detect Overfitting in Exploratory Data Analysis
Overfitting is a common pitfall in data analysis and modeling, where a model learns the noise in the training data rather than the underlying patterns. While overfitting is most often discussed in the context of predictive modeling, it can also manifest during the exploratory data analysis (EDA) phase if insights or hypotheses are drawn too…

How to Detect Outliers Using Tukey’s Fences in EDA
Detecting outliers is an essential part of Exploratory Data Analysis (EDA) to ensure data integrity before applying statistical models. One of the most effective techniques for detecting outliers is Tukey’s Fences, which uses the interquartile range (IQR) to identify data points that significantly deviate from the rest of the dataset. Here’s a breakdown of how…

How to Detect Multicollinearity in Your Dataset Using EDA
Multicollinearity is a common issue in statistical models, particularly in regression analysis, where predictor variables are highly correlated with each other. This can lead to unreliable estimates of regression coefficients, inflating standard errors, and reducing the overall predictive power of the model. Detecting multicollinearity early in the data analysis process can help ensure more accurate…
