How do you compute a percent error?
% error = |experimental value - theoretical value|/theoretical value * 100% It is the absolute value of the differe nce betwee n the experime ntal a nd theoretical values divided by the theoretical value multiplied by 100%.
When a study is designed so that neither the subjects nor the experimenters know which subjects are in the treatment group and which ones are in the control group the study is called a experime?
The study is called a double-blind study. This helps to reduce bias and ensure that the results of the study are not influenced by the expectations or beliefs of either the subjects or the experimenters.
How weighing by difference eliminates systematic balance error in analysis of an unknown acetic acid solution experime?
Weighing by difference involves weighing the container before and after transferring the substance. By subtracting the initial weight of the container from the final, any systematic balance error present in the weighing process is eliminated. This method ensures that the mass of the substance is accurately measured without the influence of balance errors.
Describe an experiment which can be used to investigate the effect of gamma radiation on mongo seeds include a description of how the dose can be varied and how you can set up controls in the experime?
To investigate the effect of gamma radiation on mongo seeds, you can set up an experiment where you expose a group of seeds to varying doses of gamma radiation (e.g., 0 Gy, 10 Gy, 20 Gy, 30 Gy). This can be achieved using a radiation source where the distance and exposure time can be adjusted to control the dose. For controls, you can have a group of seeds that are not exposed to any radiation (0 Gy) to compare with the irradiated seeds. Additionally, you can have another control group exposed to a standardized dose to provide a reference for the experimental results.
