Introduction+to+Quantitative+techniques+for+HL+students

This area of the Wiki is here to give HL students an introduction to the quantitative skills and techniques that are required to succeed in the HL Paper 3.

Here is a quick activity to remind you about some of the things you did in IGCSE



What is the table below telling us about the relationship between the two variables?



Now calculate the % change in GDP What is this growth in GDP better known as?  And another percentage question



Positive and negative relationships



Representation of data in Economics

Work out the percentages in each income group from the data below. How best would you represent this data in graphical form? 

What is happening to agricultural output per worker between 1996 and 2000? <span style="font-family: 'Trebuchet MS',Helvetica,sans-serif; font-size: 16px;">

<span style="font-family: 'Trebuchet MS',Helvetica,sans-serif; font-size: 16px;">Linear Equations:

<span style="font-family: 'Trebuchet MS',Helvetica,sans-serif; font-size: 16px;">This is a mathematical skill you will use a lot in the coming months. Let's say you had the following equation. How would you work it out if you are given the following information:

<span style="font-family: 'Trebuchet MS',Helvetica,sans-serif; font-size: 16px;">A= 100- 2P

<span style="font-family: 'Trebuchet MS',Helvetica,sans-serif; font-size: 16px;">When <span style="font-family: 'Trebuchet MS',Helvetica,sans-serif; font-size: 16px;">P = 0? <span style="font-family: 'Trebuchet MS',Helvetica,sans-serif; font-size: 16px;">P=10 <span style="font-family: 'Trebuchet MS',Helvetica,sans-serif; font-size: 16px;">P=20 <span style="font-family: 'Trebuchet MS',Helvetica,sans-serif; font-size: 16px;">P=30 <span style="font-family: 'Trebuchet MS',Helvetica,sans-serif; font-size: 16px;">P=40 <span style="font-family: 'Trebuchet MS',Helvetica,sans-serif; font-size: 16px;">P=50

<span style="font-family: 'Trebuchet MS',Helvetica,sans-serif; font-size: 16px;">Plot this on a piece of graph paper with P being on the vertical axis?
