PDF-Unit 6: Standard Deviation | Student Guide | Page 1

Unit 6 Standard Deviation Summary of Video The video begins with a tale of two cities Portland Oregon and Montreal Quebec The average monthly precipitation in these two cities is similar 15. We will do this by pulling together everybodys data then calculating the average standard deviation and relative stand ard deviation You can then compare your data with the average of everybodys data The average result is calculated by summing t Let’s start with an example. I divided the class into 2 teams, A and B. Coincidentally, the quiz average for team A is the same as team B, 81.5. So we expect a graph of their scores to be about the same, right?. Standard Deviation. . summarizes . the amount . each value . deviates. from . the mean. . . SD. . tells us how . spread out . the data items are in our data set.. If data . is close together, . standard will . First center (expected value). Now - spread. 4.2 (cont.) Standard Deviation of a Discrete Random Variable. Measures how “spread out” the random variable is. Summarizing data and probability. Data. Objectives:. To calculate and interpret the standard deviation of a data set. To compare the standard deviation of data sets. Warm-up: Complete Problem 1, Questions 1 – 5, on pages 490 – 491.. Use. Kevin McLeod & Chris Horton. OCE, Region 12 Houston. 1. Introduction. Brief discussion of history and scope. Review of compliance documents. Investigation process. 2. Clean Air Act. 1977 Clean Air Act. Unusual Values. . . Ruisheng. Zhao. OER – . www.helpyourmath.com. . What is the MEAN?. How do we find it?. The mean is the numerical average of the data set, and we use the mean to describe the data set with a single value that represents the center of the data. Many statistical analyses use the mean as a standard measure of the center of the distribution of the data.. 1. 0. In addition to level 3.0 and above and beyond what was taught in class,  the student may:. · Make connection with other concepts in math. · Make connection with other content areas.. The student will summarize, represent, and interpret data on a single count or measurement variable.. Analyze the spread of data.. 4. 3. 2. 1. 0. In addition to level 3.0 and above and beyond what was taught in class,  the student may:. · Make connection with other concepts in math. · Make connection with other content areas.. Standard Deviation. Standard Deviation – measure . how spread out the data is from the mean. Lower standard deviation:. Data is . closer to the mean. Greater likelihood that the independent variable is causing the changes in the dependent variable. Analyze the spread of data.. 4. 3. 2. 1. 0. In addition to level 3.0 and above and beyond what was taught in class,  the student may:. · Make connection with other concepts in math. · Make connection with other content areas.. Obj. : The student will be able to . . 1) Calculate standard deviation. . 2) Calculate mean deviation. HWK: Worksheet. Vocab: 1) standard deviation – a measure of how spread out the numbers are. Since the averages are the same, can we assume that the students in both classes all did pretty much the same on the exam?. The answer is… No.. The average (mean) does not tell us anything about the distribution or variation in the grades..
