Description

In this activity, students explore different ways of creating simple bar graphs and adding error bars from calculated statistical values using built-in functions in Excel or Google Sheets. Students apply what they learned by plotting beak size measurements of Galapágos finches collected before and after a drought.

This activity covers statistical concepts including standard error of the mean and confidence interval.

Student Learning Targets

Use a spreadsheet program to calculate the standard error of the mean for a sample data set.
Create a bar graph and add error bars showing the standard error of the mean.

Estimated Time

One to two 50-minute class periods.

Key Terms
