As a measure of central tendency, it answers the question, where do most values fall? In statistics, we work with population and sample means, each having its own symbol and formula.
Mean, median, and mode are different measures of center in a numerical data set. They each try to summarize a dataset with a single number to represent a "typical" data point from the dataset. Mean: The "average" number; found by adding all data points and dividing by the number of data points.

- I have a problem with the "median" question. I've sorted and then chosen the answer but check failed...i am a teacher and it says sort the data from least to greatest in the quextion you need to arrange the values first than solve the answer will be 8
- Can there be negative infinity?Yep, you can just keep getting more and more negative.
- What if there would be same number of repeated number exist in the list? for example set: 5,10,10,8,...I believe you would list them both. So in your case, the modes would be 8 and 10 since they both occur at the same time. I hope this helps!
