Calculate the mean of the following rainfall data: 5 mm, 10 mm, 20 mm.
Add all the measurements and divide by how many there are.
What is the mode of the data set: 5 mm, 5 mm, 10 mm, 20 mm?
Look for the value that appears more than once.
What does the mean represent in a dataset?
Think about how different values contribute to an overall average.
True or False: The median is less affected by outliers than the mean.
Why would that be important in analyzing data?
You have rainfall data recorded in inches: 1, 2, 2, 2, 3, 4, 100. Calculate the mean, median, and mode.
Consider how the outlier, 100, affects your calculations.
Analyze a dataset: 5 mm, 10 mm, 15 mm, 20 mm, and 90 mm. How do mean and median compare, and what does this tell you?
