This project incorporates spreadsheets with scatter plots and lines of best fit. It asked students to perform various regressions, such as linear, power, exponential, and logarithmic, The students are asked to generate an model to help park rangers determine the weight of black bears by using only one of three measures, neck girth, length, and chest girth. Calculating the bears weights allow the rangers to anesthetize them in order for them to care for the bears. The r values in this project
