Karen Horovitz 7 September 2009 CHM231 Expt 1: Mathcad Computers are used to both acquire and analyze data from all chemical instruments that measure physical properties. Learning about the way a PC works as well as its components will aid in understanding how data is stored on a USB device as well as on the hard drive for archiving and backup purposes (see Figure 1). Furthermore, data analysis also required software such as Excel, Mathcad, and Hyperchem to be used. In order to introduce students to these types of functions, this lab will teach basic excel programming to conduct statistical and error analysis on given data. Figure 1: In this laboratory, Excel will be used to model a radial distribution function, first order kinetics plots, standard deviations, and regressions. An plot of the data is made, and the radial distribution function will then be

Unformatted text preview: applied. For the first order kinetics plot, a linear plot of the natural log of the concentration vs. time is made and the slope and intercept are Memory Disk Monitor CRT Keyboar d Mouse Printer Serial GPIB ↑↓ ↑↓ ↑↓ ↑↓ ↑↓ ↑↓ I/O Bus ↑↓ CPU ↓ ↓ found by adding a linear trendline. The R squared value is displayed on the chart, and the residuals are calculated and plotted. To check the R squared values, statistical analysis equations are used. In the third experiment, a new data set is inputted into an excel spreadsheet. After plotting both values and adding a linear trendline, the average and standard deviation of each column are calculated. Then, the formal covariance and correlation coefficient are calculated. This analysis is repeated for the correlation between student height and final score....
