C) Mode and this is why. Mode is the number that occurs most often. So lets say 1 is lettuce, 2 is ketchup, and 3 is mustard. IF you have 4 students that like lettuce, 2 people that like ketchup, and 1 person that likes mustard on their hamburger. Then it would look like so 1, 1, 1, 1, 2, 2, 3. 1 occurs most often making it the most popular hamburger condiment. Mean is when you add all of the numbers up and divide them by how many numbers there are. Median is the middle number. Range is the difference from the lowest to the highest number. I hope this helped. If you have any further questions feel free to ask. Also if this is not what you are looking for please message me with what was wrong. :)
