AP STATISTICS

​Statistical concepts can become confusing if we don't understand what they represent. A scaled score is a standardized score that helps us to compare two different results in two different scales, but how is it similar or different from a standard score? Understanding not just the concepts but its relationships will give us powerful tools to explore and interpret the data. Everything we need is in the data; we need to identify patterns and infer conclusions.

Statistics help us to interpret our surroundings, avoiding our own biases. That's why we say the 'math is the language of the Universe,' because the Universe uses it to express itself, and we use it to understand the Universe. To me, the AP Statistics exam is one of the most relevant tests. The exam assesses the skills of students collecting, analyzing, and drawing conclusions from data. The information on this website is designed to help you understand the concepts, interpret data, and make informed decisions based on the results.
