Challenge Problems
Push your limits with advanced challenges
Using a provided dataset for an experiment, plot the data points, include appropriate error bars, and fit a best-fit line. Calculate the correlation coefficient and analyze the residuals for patterns.
💡 Hint: Think about both visual representation and statistical analysis when presenting your findings.
Design a graph that incorporates data points from two different experimental methods, each with varying error rates. Discuss how you would represent this effectively while ensuring clarity.
💡 Hint: Focus on clarity—how will your audience understand the differences?
