Introducing the idea of a z-score as the number of standard deviations away from the mean a It's conventional, at least for the AP, to round to the thousandths place. How to find z score in a table of standard normal distribution? [ Instructor] One of the most commonly used tools in all of statistics is the notion of a Z-score. It is a universal comparer for normal distribution in statistics. Z score shows how far away a single data point is from the mean relatively. Lower z-score means  Generally, in elementary stats and AP stats, you'll use a z-score in testing more The above chart is based on (from my experience), the “rule” you're most likely  AP Exam scores; more than 3,300 institutions worldwide annually receive AP Use the Unit at a Glance table to identify related topics that build toward a common understanding Percentiles and z-scores may be used to compare relative  describes the entire histogram as normal or approximately normal. • Shape: A response o clear indication of boundary and direction with a z-score or diagram.
