Mean is found by _________________________ .

• finding the sum of the data
• finding the middle
• finding the sum of the data, then dividing by the amount of numbers
• subtracting the minimum minus the maximum

When finding the median, what do you do if there are two middle numbers? (a)  

• Give up
• Pick one
• Write them both as your answer
• Add them together and divide by 2
