Greatest price: _____________________ Smallest price: _______________________ Step 2: Subtract the two numbers to get the range. The range of prices of the restaurant is __________________________ Activity #2 Directions: Find the range for each data set. Follow the model. Test Practice The chart shows the record lengths of six venomous snakes found in Florida. What is the range of the snake lengths? Ordered list: ________________________________________ Range: ________-__________=______
- 4. Activity #3 Score:_________/0,42 each Directions: Find the mode and range in each of the sets of data below. Follow the model. GREAT SUCCESS!
