1. The Rule of _____________ for making a Data Table! T  __________ (Comparing Your D.V & I.V.) H  ___________ (I.V. Column 1 st, D.V. 2 nd, Avg. @ End!) U  __________ (Where they Apply!) M  _________________Organized! B  _________or Boxes (Around your Data!) *I.V. = Independent Variable & D.V. = Dependent Variable

2. __________________ VariableDependent Variable (______) Example 1: “ Title – Comparing D.V. to I.V. ” * If I wanted to see how fertilizer affected the growth of a plant and I gathered the following data: A plant was given no fertilizer and grew 5 cm, Another was given 1 gram of fertilizer and grew 7 cm, and the last was given 2 grams of fertilizer and grew 10 cm. I could then organize that data accordingly into a table! Title = ___________________(cm) vs. The _________ of Fertilizer Received Amount of Fertilizer Received (_____________) Plant Growth (Centimeters = ____) No Fertilizer5 cm 1 gram7 cm 2 grams10 cm

3. Independent Variable ____________________ Variable (Units) ___________ _(Units) Trial 1Trial 2Trial 3 Example 2: “ Title – Comparing D.V. to I.V. ” * An experiment tested three different insects (spider, ant & beetle) to see which one ran a certain distance (3 meters) the quickest. Each insect was given 3 chances (trials); here was the data collected: Spider  Trial 1 = 12 seconds, T 2 = 11 sec, and T 3 = 10 sec. Ant  Trial 1 = 22 sec, T2 = 23 sec, and T 3 = 21 sec. The Beetle  T1 = 7 sec, T2 = 6 sec, T3 = 5 sec. Organize the Data in a Table according to T.H.U.M.B. ! Title = Time in ______________ vs. Different __________ Different Insects Time in (Seconds = sec) Average (sec) Trial 1Trial 2Trial 3 12 sec11 sec10 sec11 sec Ant22 sec23 sec21 sec22 sec 7 sec6 sec5 sec6 sec

4. YOUR TURN: I collected the following data: Student 1 received an 80% on their Biology test, Student 2 = 85%, Student 3 = 75% and Student 4 = 98%. *Create your table using THUMB below: Percentage on Biology Test (%) Student 180% Student 285% Student 3 Student 498% Biology Test Percentage vs. Students Tested

5. A little Tougher Now: 4 kids (2 boys and 2 girls), were tested to see how long it took to clean their rooms each day for 3 consecutive days; the data is as follows: Shelly took 1 hour on day 1, 45 minutes on day 2 and 1 hour 10 minutes on day 3. Tom took 45 minutes on day 1, 2 hours on day 2 and 1 hour 30 minutes on day 3. Rich took 2 hours on day 1, 3 hours on day 2 and 2 hours on day 3. Jenny took 30 minutes on day 1, 35 minutes on day 2, and 40 minutes on day 3. Averages time take to clean the room was: Shelly = *Create your table using THUMB below: ______How Fast They __________ Their Rooms Each Day (Hours = ___ & Minutes = ____) Average Time Taken Day 1Day 2Day 3 1 hr45 min1 hr 10 min 58 min Tom45 min2 hrs1 hr 30 min 1 hr 25 min 2 hrs3 hrs2 hrs2 hrs 20 min Jenny30 min35 min40 min35 min Time it Took to Clean Their Room Each Day vs Kids
