Each day, Leila records the number of news articles she reads. Here are her results for the last nine days.

6, 3, 1, 3, 3, 8, 6, 3, 8

Find the range and the mode for the data.

The mode is whatever number that repeats itself the most, which would be 3 in this case. To find the range you would find the difference between the highest number and the lowest number. The highest number is 8 and the lowest is 1 so 8-1=7. The range is 7.
