Regents Review Sessions with Ms. Angelino – S

In anticipation for the Algebra Regents on Tuesday, June 12, PS/IS 78Q will be holding private, teacher-led, video conferencing sessions on ezTalks. Each student will have the opportunity to review prior topics, ask specific questions about past work, apply algorithms with practice questions, and review calculator applications from the comfort of their own home.

How to use the calculator to find and graph residuals:

http://mathbits.com/MathBits/TISection/Statistics2/Residuals.htm

Important things to edit:

(for step #4) cross out the first part and only follow directions after you see the word OR -> (under L3, use 2nd STAT #7 instead).

(for step #5) take note that the residual graph does not use L1 and L2.  you must change L2 to L3 (or wherever you entered the residual).
