Thursday....

Tomorrow is a fun day for all you seniors...enjoy it! Have a good time before school and at pep rally, but be smart and be safe! Don't get yourself in trouble! And don't wake up too early!

Tonight, please complete the worksheet provided in class regarding IQ scores. If you don't have it, it's uploaded under our classroom resources. Questions a-e can be completed using the Empirical or 68/95/99.7 Rule. Questions f-i are based on z-scores and the z-table. We have not learned j,k, or l...here's how to do them on your calculator:

For J,K,L:

• Press 2nd, VARS to go to the distribution menu.
• Then, choose InvNorm( 
• Type InvNorm(% to the left, mean, standard deviation)
• This will tell us the IQ score for that percentile!

For example, if I wanted to find out the IQ that marks the top 10%, I would know that means 90% are "to the left." So I would type InvNorm(0.90, 100, 15) to find the IQ that cuts off the top 10%
