1. Range = highest score - lowest

Mode is most frequently observed score, if there is one.

μ = Σx/n

Median is score with middle-most value. If two score are middle-most, find mean (μ) of the two middle-most values. Median = 50 percentile.

What is range? From the lowest value to the highest value. I suppose you're talking about the terms that apply to the concept of function. The most common definition for this term is the set of values for the dependent variable.
