Math-1530-05/08/12/13 Probability & Statistics Spring 2005 / Video#2 STATISTICS : Decisions Through Data Name:______________________ Data Analysis for One Variable (Units 7 - 10) Section:______ Directions: Watch the video and briefly explain the statistical meanings of the following terms & symbols and answer relevant questions. (For those who write LARGE: Increase spacing between the terms in this list before printing or use additional paper as needed.) Staple or clip your library receipt for the video (not the headphones or remote control) to the top left corner of the page(s). Histogram: Skewed: Variation: Density Curve: What is the total area under any density curve? Symmetric: Normal Distribution: Median: Mean: x (x-bar):  : Spread: Standard Deviation (std dev, for short):  : How is the std dev used in measuring area under a Normal curve? Explain the 68-95-99.7% rule. Where is the tail of a density curve? Standardize/standardization: How can we compare two or more measurements that come from different Normal distributions? Standardized measurement: Standard Normal Curve (SNC): What are the values of mu and sigma for the SNC? Standard Normal Table: Where is this table located in your textbook? Which z-scores have negative values? The video lists two specific applications of the Normal Curve Calculations. What are they? In class, I call the first application a forward problem and the second application, a backward problem. In the boxes below, outline the steps to carry out the appropriate calculations for each application. Forward problem: Backward problem: OMIT UNITS 9 and 10!
