Visualization is a powerful tool for finding unusual data points, also known as outliers. Here’s how it can help:
Graphs Make It Clear: Using graphs like scatter plots, box plots, and histograms can help outliers stand out. For example, in a scatter plot, it’s easy to see a data point sitting far away from the rest. The other points may be close together, but the outlier is way off in a corner.
See the Big Picture: Visuals let you see how your data is spread out. With a box plot, you can quickly spot values that don’t fit in, especially those that are outside the lines called whiskers. These can be good clues that something is unusual.
Easier to Understand: Looking at pictures of data is often simpler than reading raw numbers. You might find patterns and oddities just by glancing at colorful graphs, making the information easier to digest.
By using these visualization methods in your data cleaning, you’re not only making your data better but also improving your analysis overall. Remember, visuals can really help you find those hidden outliers!
