Exploratory Data Analysis (EDA)
The data analysis approach includes techniques that aim to give a short description of key characteristics through the use of visual methods.
Graphical Techniques
- Scatter Plots: Charts indicating the correlation between two variables with their values. Periodically, each mark in the grid stands for an observation.
- Box Plots: The chart displays raw data that indicate distribution through their quartiles. They can highlight outliers.
- Stem-and-Leaf Plots: A statistic demonstrates how data is evenly distributed. We assign each number to be the stem (the first part) and the leaf (the last digit).
Types of Statistical Data Analysis
Statistics data analysis is a class of analysis that includes different techniques and methods for collection, data analysis, interpretation and presentation of data. Knowing the approach to data analysis is one of the crucial aspects that allows drawing a meaningful conclusion. In this article, the most fundamental types of statistical data analysis will be described. The authors will explain all the terms and concepts easily.
