Data exploration is the initial process in data analysis that aims to understand the characteristics, structure, and patterns in a dataset. This stage involves using statistical and visualization techniques to identify distributions, relationships between variables, missing values, and outliers. Data exploration helps researchers gain initial insights into the data, so as to make better decisions in the selection of subsequent analysis and modeling methods.

Data collection is an important first step in analysis, where data can be obtained through observation, interviews, questionnaires, or experiments. Once the data is collected, data presentation is done to facilitate understanding, usually in the form of tables, graphs, or diagrams. One effective visual tool for presenting quantitative data is the Box Plot. A Box Plot illustrates the distribution of data, displays medians, quartiles, and helps identify outliers. With Box Plots, we can quickly understand the distribution and variation in the data.
A good understanding of data collection and presentation, including the use of Box Plots, helps in more informed analysis and decision-making.
