AP Statistics Preparation

AP statistics is such an interesting subject to me. To think that the so many relationships and associations in the world can be described with numbers is fascinating. I’ve learned about data analysis, outliers identifications, and even model creations to describe relationships between two variables. For example, one can collect data on the relationships between ice-cream sales and outside temperature, and create a model for it. Based on the model, we can see how strong the relationship is using correlation equation and be able to predict the number of ice-cream sales based on the outside temperature.

Taking PSAT

On Saturday October 7th 2017, my friends at LLA and I took the PSAT on Khan Academy. We all arrived at around 7:45am and went to our separate rooms. The practice exam started and we all sat through the whole exam with breaks between each session.
