Last but not least, please do not forget to express your love and gratitude to your wonderful mom! Happy Mothers’ Day to all mothers!
Nice to work with you today! We did a quick quiz on “Exponential Growth” and reviewed percentages. Please check the notes for your review, and finish Test Innovators homework before May. 2nd.
There will be no school in the following two weeks. Enjoy your spring break, and see you on May 3rd! We will take DSAT#9 when we are back.
Comments Off on SAT Math L15: Inference from sample statistics and margin of error
Dear Students,
It’s so nice to work with you~ Today we reviewed problems in DSAT#8 and learned Inference from sample statistics and margin of error. Here are the notes for your review.
Key concepts:
1. random sampling
2. the larger the sample size, the smaller the margin of error
Please finish the assignments on Test Innovators, and fill out the Question Form to share your problems with me. We will learn L16: Percentages and take a “pop quiz” next week.
I hope you are doing well during the beautiful spring days! We took the DSAT # 8 in class today, and I am so glad to see some of you are making steady progress each time! Please use this Google Form to share your questions and I will be happy to go over them next week in class.
We will learn L15. Samples & Margin of Error next week. See you then!
Comments Off on SAT Math L13. One variable data distributions, measures of center & spread
Dear Students,
It was nice working with you today! We went over the questions in DSAT#7, and learned many basic terms and concepts in Statistics:
mean, median, mode, range
weighted mean formula
standard deviation
Please check the notes, and finish the homework on Test Innovators before next Sunday. Please fill in the Google Form to let me know which questions you would like Ms. Li to go over.
One variable data distributions and measures of center and spread
We hope you had a wonderful winter break. We went over problems from DSAT#6, and learned L12: Nonlinear Functions. Please check the notes for your review, and finish the homework on Test Innovators (complete at least 6 sessions). Do not forget to share your questions with me via this Question Form.
Hope you enjoy these two short videos about the Quadratic Formula!
Take care! I look forward to meeting you all next Sunday!
Nice to work with you today in class! We went over questions from DSAT#5 and reviewed key points about quadratic equations. We also took an exit ticket in class.
Please check the notes here, and master the standard form (or general form), vertex from, factored form (or intercepts form), and the formula to find the axis of symmetry and vertex.
Homework (on Test Innovator): Complete 6 out of 9 sessions in Nonlinear equations in one variable and systems of equations in two variables. Share your questions on the Google Form before next class.
There is no school next week. Spring Term starts on Jan. 25th. See you then!
Best, Ms. Li
PS: Please sign up for the Spring Term if you have not done so. Check the school website for further information.
