Transcript

  • 1. RUNNING SCORES!!!By Emily, Zoe and Trinity
  • 2. PREDICTION  Wepredict that the longer the distance the slower you run.
  • 3. OUR DATA!!! 25 20 15 20meters 50meters 10 100meters 5 0 Zoe Trinity Emily Nick
  • 4. RANGE!!!  20meters: 1.5 seconds  50meters: 2.2 seconds  100meters: 3.5 seconds
  • 5. MODE!!! We can’t find a mode because the data is continuous and so every value is different.
  • 6. MEDIAN Wecan’t exactly do median because there are only 4 people, so there is no middle value!
  • 7. MEAN  20meters: 4.7 sec  50meters: 9.4 sec  100meters: 19.4 sec
  • 8. SPEED We need to know speed so we can decide if our prediction is correct.Average speeds 20 m = 4.26 m/s 50 m = 5.32 m/s 100 m = 5.15 m/s
  • 9. DISCUSSION The range gets bigger as the distance gets longer. Zoewas the fastest and Emily was the slowest in all 3 of the races. Our prediction was incorrect. We did not run slower for the longer distances.
