Visualizations help to understand patterns in data from "summary" of R for Data Science by Hadley Wickham,Garrett Grolemund
Visualizations are a powerful tool for understanding patterns in data. By representing data visually, we can more easily identify trends, anomalies, and relationships that may not be apparent from looking at the raw numbers alone. For example, a line graph can show how a variable changes over time, allowing us to see if there are any consistent trends or fluctuations. A scatter plot can help us identify correlations between two variables, revealing if there is a relationship between them. Histograms and density plots are useful for understanding the distribution of a single variable, showing us if the data is skewed, bimodal, or normally distributed. By exploring data through visualizations, we can gain insights that may not be immediately obvious when looking at tables of numbers. Visualizations can also help us communicate our findings to others more effectively. A well-designed plot can convey complex information in a way that is easy to understand, allowing us to tell a compelling story with our data.- Visualizations can help us spot errors or inconsistencies in our data. For example, outliers may be more apparent in a box plot than in a list of numbers, prompting us to investigate further and potentially uncover data entry mistakes or other issues. By exploring our data visually, we can ensure that our analyses are based on accurate and reliable information. Overall, visualizations are an essential tool for anyone working with data. They allow us to explore, understand, and communicate our findings in a way that is both intuitive and informative. Whether we are analyzing sales figures, survey responses, or experimental results, visualizations can help us unlock the patterns and insights hidden within our data.
