1.) First, please complete these questions--use your notes on shifting/rescaling for 3 and 11!
- Page 123: 1ab, 3, 11
- *The formula used to convert SAT/ACT scores in #3 is outdated, so you can't apply this to your own scores.
2.) Read the following pages in your textbook and record the answers to the questions listed in your notes--this is you teaching yourself stuff about z-scores--we'll quickly move through/review these ideas in class on Monday!
- Read the sections "The Standard Deviation as a Ruler" and "Standardizing with Z Scores" on pages 102-104
- Record the following in your notes: (you can title this "Z Scores" and list all of this information below that title in your notes)
- What is the formula for a z score?
- What is a standardized value?
- What are the units for a standardized value?
- What does a z-score measure?
- What do we consider "more unusual" when comparing data values?
- Optional--read the sections about shifting and rescaling
- Read the sections "Back to Z Scores" and "Working with Standardized Variables: Step by Step" on pages 106-107
- Record the following in your notes:
- Write the 3 italicized bullets about standardizing
- The step by step example shows how we can use z-scores to answer a question--nothing to write in your notes here, but read this carefully to develop your understanding!
- Look at the glossary on page 122...
- Record the following in your notes:
- List and define each of these terms from the glossary:
- Standardizing
- Standardized value
- Z Score
- (This info was addressed previously as well, but that's ok--the more we write stuff down, the more we'l remember it)
On Monday we'll get back into some notes on chapter 6! We'll start class with a stamp problem based on your reading, so come prepared! See you there!
