Kelvin is running an experiment on the growth of fern house plants with artificial light versus real light. Which option would have the least amount of bias during the random selection process?(1 point)
Responses
a. Assigning a number to each plant and using a random number generator to select the sample.
b. Selecting the largest 20 fern house plants to run the experiment on.
c. Selecting the first 20 fern house plants closest to the door of the plant nursery.
d. Choosing the 20 most beautiful fern house plants to run the experiment on.
Which one is the correct answer and explain why it is the correct answer.
a. Assigning a number to each plant and using a random number generator to select the sample.
This option would have the least amount of bias during the random selection process because it ensures that every plant has an equal chance of being selected for the experiment. This method removes any potential biases that could be present in the other options such as size, location, or subjective beauty. By using a random number generator, Kelvin can ensure that the selection process is fair and unbiased.
