1. You have a volume of strong acid, pH near 0. You perform a titration curve, measuring pH as you add a strong liquid alkalai in volume increments. Would you plot the data?
Yes
No
2. A local newspaper has asked you, the local weather expert, for the daily high temperatures for the last two weeks (2nd through 14th of July). From the first through the 7th the daily high was 96 degrees. You measured 95 degrees from the 8th through the 14th. A picture is worth a thousand words, correct? Would you give them a graph?
Yes
No
3. Today your newspaper asked you for daily precipitation totals for last month. Last month saw precipation almost every day, with amounts ranging from a trace to over 2 inches. Would a graph be an appropriate way to communicate this information?
Yes
No
4. Animals were fed different diets for a month and their masses were taken at the end of the experiment. Three groups of 10 animals per group were sorted out at the start of the experiment so that groups 1-3 had mean masses per animal of 210 ± 3, 211 ± 3.5, and 209 ± 3 grams, respectively. At the end of the experiment mean masses per animal for groups 1-3 were 305 ± 65, 365 ± 46, and 246 ± 43 grams, respectively. Would you plot these data?
Yes
No
5. The transit method for detecting extrasolar planets (planets orbiting a star other than the sun) involves measuring a star's brightness over time. Periodic dimming of light coming from a star suggests that something may be passing in front of it, blocking its light. These kinds of data are subject to considerable experimental error. Let us suppose that you used this method to find a star that may indeed be hosting a planet. would you plot the data?
Yes
No
*6. Your undergraduate mechanics laboratory class is equipped with filming equipment and very sophisticated "frictionless" inclines for testing Newton's laws of motion. You rolled a steel ball from point A at the top of a 45 degree incline to point B at the bottom, taking very precise time/distance measurements at 20 evenly distributed points along the pathway. To determine whether or not friction significantly influenced the motion of the steel ball should you plot these data?
Yes
No
