California Black Worms Lab
By: Jessica Zelaya
This week in my bio class we did, it so obvious, a California Black Worms Lab! Our objective was to figure out which is the depressant, stimulant and normal water that worms were in. There were label A,B and C.
We did 2 days of data and share our data with other groups in are class.
I can conclude that the depressant is B, stimulant is A and normal is C. My method is to average the 2 days within each group, then make a scatter plot to determine the overall average. I exclude the groups who did not do data for two days. the reason why is that i am taking the average number of both and it would be bias if i use numbers that were not. Group A have 30 points and B and C have 25 points, there is a little bias. However you can still see that B is more toward the lower numbers, which means that more heart rates where slower. A is more toward the higher numbers, which means that more heart rates where faster. The only way you can really tell for A and B is C, C was spread out and have more points toward the middle of the graph.
