Today Joshua and I started out by going through the AP Classroom FRQ he had for homework last night. He got 4 out of the 6 points for it. He did a good job, but made an error on rounding and notation (which is an error he doesn't usually make). Next, we took notes in 2.15 on Semi-log plots. We learned that this is a different way to represent data in a way that we are used to. We recognized when we do this that the information looks linear. We used our calculator to create a linear regression model. Then we used it to predict future values.
