I could buy a flower seed packet from grocery outlet. I open the packet finding 10 sunflower seeds, i used a even number generator to determine what amount of seeds to plant. The generator lands on 4. i plant 2 sunflower seeds in 2 pots of soil and plant the other 2 sunflower seeds in 2 pots of sand. I also will water each plant every day and ensure each plant has the same amount of sunlight. Then I can measure the height of the sunflowers after one month

Where in your experiment would random selection occur?

GPT-4o mini · Answer

In your experiment, random selection would occur when you used the even number generator to determine the amount of seeds to plant. Specifically, the act of randomly selecting the number of seeds to plant (which was determined to be 4) is a form of random selection, as it introduces an element of chance in deciding how many seeds will be used for planting.

However, if you were allowing the random selection of which specific seeds to plant out of the 10 sunflower seeds (for example, if you had a larger set of seeds and were randomly choosing some to plant), that would also be another example of random selection. Since you only specified selecting an even number (4), this is the main point of random selection in your experiment as described.

Overall, random selection helps ensure that the choice of how many seeds to plant is not influenced by personal preferences or biases, which can help improve the validity of the experiment.
