RANDOM VARIABLES Definition usually denoted as X or Y or even Z and it is th e numerical outcome of a random process Example random process The number of heads in 10 tosses of a coin Example The number 5 rating Environmental issues. Naturally occurring variables: usual with several groups of people. Noise. Temperature. Light. Time of day. Seating arrangements. Artificiality:. Classroom or Office are not “real world” or “natural”. Types of Variables. There are 2 main types of variables: . Independent Variable: . The variable that is changed by the scientist; the ‘. I control. ’ variable. Dependent Variable: . The variable that might change because of what the scientist changes – what is being measured . 2-Stage . and 3-Stage Least .

Objective. Essential Question. Key Vocab. To translate words into algebraic expressions and equations. In what order are the terms written in the expression “less than?” (i.e. 5 less than 4). Introduction to C++. CS1 Lesson 2 -- John Cole. 1. Parts of a C++ Program. // sample C++ program. #include <iostream>. using namespace std;. int main() . {. cout << "Hello, there!";. return 0;. Java Unit 11: Inheritance I. Both instance variables and methods are inherited. In a program that uses an instance of a subclass, it is possible to work with the object’s instance variables by using the corresponding get and set methods, which are also inherited from the superclass. .
