Sampling: the group of things you want to use to check your hypothesis

Primary Data: Data you collect yourself

Continuous Data: Numerical data that has an infinite number of values (often seen with height, distance, time)

Spread: the distance/ how spread out/ variation of data

Average: A measure of central tendency - or the typical value of all the data together

Proportion: numerical relationship that compares two things
