Chemistry 365 Biochemistry Laboratory Unit #1 Tables and Figures with a Spreadsheet References : Robyt, J.F.; White, B.J. Biochemical Techniques Theory and Practice ; Waveland: Prospect Heights, IL, 1990. The objective of this project is to teach you the general operation of the spreadsheet program that you will be using to construct tables and figures for your laboratory project reports. Scientific data are quickly and easily processed and can be presented professionally with the use of a spreadsheet program. Repetitive calculations, correction of mistakes, and graphing are all conveniently performed. The spreadsheet program we will use is Microsoft Excel, available on the campus computer network. Tables and Figures (graphs): Experimental data are best presented as tables and/or figures, which offer a concise and rapid method of communicating to the reader the data collected and the experimental results obtained. Both tables and figures should have explanatory titles and should contain enough information to be intelligible without reference to the text. Tables require careful labeling of all data presented. Every row and column should have an appropriate heading or label, and any codes or abbreviations should be explained in a footnote to the table. The units of all measurements should be specified. If the condition is the same for all tabulated data, this is indicated at the top of the column. It is not wise to put too much data into a single table. Use of several tables will emphasize or highlight the important aspects of the data. Do not include more significant figures than are justified by the accuracy of the determinations. Figures (graphs) are used to illustrate quantitative data and can quickly indicate the relationship between two or more variables and any special trends that might be present. There are several important rules for making good figures. Rule 1: Always label both the y-axis (ordinate) and the x-axis (abscissa). Place the dependent variable(s) on the ordinate and the independent variable on the abscissa. If possible, enclose the top and right-hand sides of the figure.

    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.
