Question

1. (5 points) You have conducted an experiment wherein you treated breast cancer cells with a variety of different compounds (A, B, and C) or a vehicle control. Your measured parameter was cell death, and you measured via trypan blue exclusion. The percent of trypan blue positive cells is tabulated below. Keeping in mind our discussion of data representation and statistics, draw an appropriate graph that represents these data and indicate what (if any) statistics are appropriate. Treatment Experiment 1 Experiment 2 Experiment 3 Experiment 4 Vehicle 3% 5% 2% 4% A 5% 7% 4% 8% В 20% 17% 21% 19% С 13% 11 % 12% 14%

Answer 1

There are four different experiments where breast cancer cells are treated with a variety of different compounds (A, B and C) and a vehicle control. These data can be represented by a clustered bar chart. The appropriate test statistic for this data is analysis of variance (ANOVA). The diagram is represented below,
