Like before, more research for Ant’s classes. When did it become a maths course?

*Instantiation:*

In programming instantiation is the creation of an instance, a particular realisation, a template such as a class of objects or a computer process. To instantiate is to create an instance where one object is given a class, name and location in a physical place; much the same way as when data is entered into a database or spreadsheet.

In object oriented programming, to instantiate a class is to create an object with an executable file that can be ran on a computer.

**While Loop:**

A While Loop is a control statement which allows code to be repeatedly executed based on a given condition and can be thought of a as a repeating IF statement.

The While Loop construct consists of a block of code and a condition/expression. The condition/expression is evaluated, and if the condition/expression is true, the code within the block is executed. This repeats until the condition/expression becomes false.

**Probability:**

Probability is a chance. It’s a number which tells you how likely something is to happen. So to get a 6 on a dice roll, the probability is a 1 in 6 chance since you’re looking for one certain number out of a possible six. To throw a coin and get heads, the probability is 1 in 2 since there’s two sides to the coin and you’re looking for one side. *(Or one in three if you’re really unlucky and the coin lands perfectly on edge which itself is a 1 in 6,000 chance due to angular momentum. Ha!)*

**Averages:**

An average is a number expressing the typical value in a set of data. It consists of three parts; mean, mode and median.

*Mean –* the average set of numbers – add them all up and divide the total by how many there is.
*Mode* – The numbers which appear most often in a set (4, 8, 7, 7, 2, 4, 7; so 7 is the Mode)
*Median* – Place the given numbers in numerical order and find the middle number. That’s the median.
