Helloo! It's Mandy, and I will be covering AP Statistics on here (as someone who got a 5 on the exam). AP Statistics is a very fun course, and it is very applicable to the real world. By achieving a 4 or 5 on this exam, you'd be able to skip an introductory statistics course in college.
To first begin for this exam, let's understand the material that is covered through the AP course material. The AP Exam can be split into 8 units.
The test can be broken up into 2 sections:
45 Multiple Choice Questions (MCQs), 2 Free Response Calculator Questions (FRQs) - 30 minutes, 4 FRQs
*You are allowed to go back and visit the Calculator FRQs, but you can't use a calculator
The test is an accumulative score of 100: 54 MCQ points and 54 FRQ Points. Each FRQ has a total of 9 points with each of these individual point contributing around 1 points toward the total composite score. Each MCQ point contributes around 1 to 2 points.
To score a 3 you need:
To score a 4 you need:
To score a 5 you need:
You’ll be introduced to how statisticians approach variation and practice representing data, describing distributions of data, and drawing conclusions based on a theoretical distribution.
