Graphing Using Excel Exercise


You are to graph each of the sets of data in each of the problems below. Be sure to include
a) gridlines when printing data tables;
b) graphs as large as possible so data and graphs print on the same page;
c) the identification of the dependent and independent variable by indicating each at the bottom of the column in your data table;
d) your name at the top of the page in bold letters;
e) the number of the problem;
f) one problem per page.

Regarding dependent and independent variables, in an experiment, the independent variable corresponds to factors you are varying and the dependent variable is the one you are measuring.
