Answer:
Range = 5, Median = 9, Mode = 7
Step-by-step explanation:
First, we put them in order from least to greatest.
So its 7, 7, 7, 8, 10, 11, 12, 12
The range is the largest number minus the smallest number, so 12-7=5. The range is 5.
The median is the number in the middle, so we cross off numbers from both sides. That leaves us with 8 and 10. The number between them is 9, so the median is 9. (the actual process to find the median if there's 2 numbers in the middle is by adding them together and dividing them by 2)
The mode is just which number appears the most often. So 7 is the mode.
