Spreadsheet Tutorial 3: Column Graphs, Error Bars, and Standard Error of the Mean
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.
