calculator. It is prefered that they know how to get the standard percent deviation formula deviation without using the statistical mode in the calculator. Their insight into the uses for the standard percentage error formula deviation will be more complete if this is so. Objectives: The student will use the Internet to find statistical data for investigations that use the mean, standard deviation, and
Percent Error Calculator
percentage error The student will calculate the standard deviation of monthly temperature means. The student will draw conclusions from the standard deviations and percentage error of these means. Materials: Access to the Internet and Netscape software. Previously set bookmark on the Netscape at the following URL for the weather report for the San Francisco Bay Area http://www2.mry.noaa.gov/nwspage/nwshome.html Scientific calculator
Can Percent Error Be Negative
Procedure: Once students have logged on to the Internet and Netscape, have them go to the San Francisco Bay Area branch of the the National Weather Service by snapping on the bookmark called NWS-San Francisco Bay Area. They should scroll down and click on Climatological Data, then scroll and click on Climate Normals and Extremes. When they reach the choice of cities, have them click on San Diego. At this point students will see a chart of weather statistics containing averages for the 12 months. The numbers we will be using are under the Temperature Means Column; specifically, the Avg column (3rd from the left.) Have students copy the 12 temperatures down. If they scroll down far enough, they will come to San Francisco-Airport and then to the San Francisco-Mission District that we want to use. Have the students find the same 12 numbers under Avg and copy those down . The question they will answer with these numbers is: Which of the 2 cities has the most consistent temperatures? This is n

This section will address accuracy, precision, mean, and deviation as related to chemical measurements in the general field of analytical chemistry.AccuracyIn analytical chemistry, the term 'accuracy' is used in relation to a chemical measurement. The International Vocabulary of Basic and General Terms in Metrology (VIM) defines accuracy of measurement as... "closeness of the agreement between the result of a measurement and a true value." The VIM reminds us that accuracy is a "qualitative concept" and that a tr

Then find the difference between each value and the average, giving you 9 deviations. Now you find the average deviation, but don't just add them together and divide by 9, you'll get zero! Give it a try and see for yourself. Instead you must convert all 9 deviations to positive numbers before you average them. There are two ways of doing this: one is called the Average Deviation and the other is called the Standard Deviation. Choose just one method: A. Average Deviation: Just convert the negative deviations to positive by ignoring the minus sign. This is called taking the "absolute value" of each number.
