Graphs and Plots Math Project

This project examines the sodium content and quality ratings of various peanut butter brands through statistical representations including histograms, circle graphs, and box-and-whisker plots. Key findings reveal the frequency of sodium levels in milligrams across brands, with a focus on natural and store-variety creamy options. The analysis includes computations of median, range, and mean values for sodium content, as well as price comparisons per serving and quality ratings. This research aids consumers in making informed choices based on health metrics and pricing.
