Chem 227 – Fall 2010 Homework 1 Part 1: visit your professor in his office by the end of the week Part 2, C1: Basic Spreadsheet Operations Due Tuesday, September 7 Objective: This exercise will introduce you to basic spreadsheet operations to perform multi-step calculations. Instructions: Import (x,y) data for a buret calibration from the file lstsqrs.csv in the homework data section of the class website into a spread sheet. Square each x-value and each y-value, and also find the product of x and y for each data point. Next, find the sum and averages of each of these columns of numbers (x, y, x 2 , y 2 , and xy). Lastly, have the spreadsheet count the number of entries in each set. Format the sheet to look nice and include appropriate column labels (e.g., x, y, x 2 , y 2 , sum x, …). You may check your results, as you work, against the key posted under Course Materials in the course Blackboard site. In your workbook, include a sheet that shows the formulas used for your spreadsheet calculations.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
