A classroom/laboratory activity to learn about linear slope, trends, confidence intervals, and Student’s t-distribution by calculating trends and uncertainties using hurricane data records over 40 years.
Using hurricane-related data for the Atlantic Ocean, students will plot graphs and determine trends by calculating linear slope. They will also calculate confidence intervals and trend values by using Student’s t-distribution.
Use this tool to help your students find answers to:
- Calculate the trend and determine the confidence interval for the frequency of hurricanes in the Atlantic Ocean (from past records).
- Calculate the trend and evaluate the uncertainty for the intensity of hurricanes (from given data).
- What are the possible effects of climate change on the intensity and number of tropical cyclones/hurricanes?
