We tested the effect of two drugs, ethanol and caffeine , on the nematode, Caenorhabditis elegans.
Pages 278-280 in the lab manual https://www.icloud.com/iclouddrive/01d_ZVIbjlxcMbHJr2wp3AZ4Q#BioLabiBook offer some explanation of confidence intervals and how to interpret them. There is also a video that demonstrates how to graph and interpret confidence intervals for your assignment.
download the excel sheet with the class data: Key – C. elegans.xlsx
Follow along in the excel sheet to calculate averages, standard deviation, and confidence intervals.
Graph the averages along with their confidence intervals.
Then, answer the following questions in a text box on your excel sheet:
What was your hypothesis?
Does the data support your hypothesis? In other words, what were the results of the experiment? To answer this, look at your graph. Is there a significant difference between Drug A and Drug B ? Did Drug A have a significant effect? Did Drug B have a significant effect?
If the data does not show significance, why might this be? Was our sample size too small? Did we have trouble consistently counting wiggles?
Please upload your calculations, graph, graph caption , and question answers as an excel file.
