Definitions - Counting numbers - the most basic numbers/ starting point for young children ex. 1, 2, 3, 4, 5, 6..... (not 0) (2 ways to think about counting numbers) -list - -counting numbers is an ordered list. Every number has a unique successor and predecessor (except 1) -cardinality - number of things in a set ex. 5 blocks, 5 cats, 5 toys one-to-one correspondence - -counting a set of objects one by one, between the list of counting numbers and the set -ex. counting blocks, ...

Population Data - everything (or everyone) we are studying. It is a set of data that consists of all possible values pertaining to a certain set of observations or an investigation. Sample Data - represents a subset of the population. It is just a small section of the population taken for the purpose of investigation. Identify the population and sample data: a university is interested in how many of their students commute to school. They randomly choose 100 students at the student center...

continuous random variable - random data that can take on any values within some interval discrete random variable - a countable set of values density curve - A mathematical model for a probability distribution of a continuous random variable uniform density curve - describes a variable that takes values that are uniformly spread between a range of values normal distribution - Common type of probability distributions for continuous random variables
