How Do Outliers Impact a Correlation Coefficient? Outliers are data points that are significantly different from the other data points. They can have a big impact on a correlation coefficient, which is a number that measures the strength and direction of the linear relationship between two variables. 📈📉 Imagine you’re in a class and you […]
Why Use a Scatterplot to Explore Correlation? A scatterplot is a graphical tool that displays the relationship between two variables. It’s like a map 🗺️ that helps us see where different variables are located. A scatterplot conveys much more information than a single correlation coefficient because it shows us the actual data points and the […]
A correlation matrix displays relationships between variables, showing positive, negative, or no correlation to help identify data patterns.
What Is a Correlation Heatmap? A correlation heatmap is a graphical tool that displays the correlation between multiple variables as a color-coded matrix. It’s like a color chart 🌈 that shows us how closely related different variables are. In a correlation heatmap, each variable is represented by a row and a column, and the cells […]
In this article, we’ll discuss how technology is used in Exploratory Data Analysis (EDA). Technology plays a significant role in EDA. There are many tools available that can help with data exploration, including statistical software, programming languages, and spreadsheets. Statistical software is commonly used for EDA. It can help with tasks such as creating charts, […]
In this article, we’ll discuss how combining data with intuition can help with the subjective and interpretive nature of Exploratory Data Analysis (EDA). When you combine data with intuition, it’s like putting together pieces of a puzzle. The data provides the pieces, and your intuition helps you figure out how they fit together. By using […]
Today, we’ll be talking about the state of mind you should have when performing Exploratory Data Analysis (EDA). When performing EDA, it’s essential to have an open and curious state of mind. It’s like being an explorer, setting out to discover new lands and see what you can find. By approaching the data with an […]
Data analysis can be a complex and daunting task, especially when dealing with large amounts of data. To make sense of it all, it’s important to create visual representations of the data using exploratory charts. In this article, we will explore best practices when creating exploratory charts, as well as common pitfalls to avoid. […]
Today, we’ll be talking about the different types of Exploratory Data Analysis (EDA). EDA is a way of exploring data through visual summaries and graphics, and there are several different types of EDA to choose from. The three main types of EDA are univariate, bivariate, and multivariate EDA. Let’s break down what each of these […]
In this article, we’ll discuss summarizing data in Exploratory Data Analysis (EDA). There are two main methods for summarizing data: numerical and visual. Numerical summaries involve using descriptive statistics to summarize the data. Descriptive statistics can help you understand the central tendency of the data (like the average), the spread of the data (like the […]
