Blood Splatter Lab 1

Question 1: How did multiple drops at each height affect your results? What is the purpose of multiple trials in a experiment?

I think the purpose of doing multiple drops at each hight because if there is an "outlier" or piece of data that doesn't make sense, you have two other blood drops to refer too. Also, having three different trials didn't affect our results dramatically, but it was useful if we had one droplet that didn't fit the rest, we didn't have to rely solely on that information.

Question 2: What did you discover about the influence of height on blood diameter in a blood spatter? could you now accurately infer the height at which a blood drop originated based on the diameter of a blood spatter? Why or why not?


I think that the higher you drop the blood from, the less accurate your blood drops will be. Many times it was hard to get the blood drop exactly in the box on the chart. I don't think I could tell what hight a blood drop was dropped from because according to our data, the diameter of each blood drop was about the same, even when dropped from higher heights.
