Question
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 I end up with (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.
What are the treatments in your experiment?
The treatment would be the soil or sand the plants grow in.
What is the response variable in your experiment?
The response variable in my experiment is the amount of plant growth
Where in your experiment would random selection occur?
Random selection occurs when the plants are chosen (from the location you are getting your plants from).
Where in your experiment would random assignment occur?
Random assignment occurs when the plants are assigned to solid or sand.

Your experiment design is quite clear, and you've made a good effort to outline the components. Let's refine some of your answers for clarity.
### Treatments in the Experiment
The treatments in your experiment are the different growing mediums: **soil** and **sand**. You are comparing the effects of these two types of growing mediums on sunflower growth.
### Response Variable
The response variable in your experiment is **the height of the sunflower plants** after one month. This is the variable you are measuring to determine the effect of the treatments (soil vs. sand).
### Random Selection
Random selection occurs when you choose the sunflower seeds from the packet. It could also apply if you were selecting from various sources of sunflower seeds or plants, but in this case, you are using seeds from a single packet.
### Random Assignment
Random assignment occurs when you assign which pots will contain soil and which will contain sand. For example, if you randomly assign the two pots receiving soil among the four total pots, that would be an example of random assignment. Alternatively, you could randomly assign the two remaining pots to receive sand.
The key here is ensuring that any inherent differences among the plants themselves are evenly distributed across the treatments to isolate the effect of the growing medium on plant growth.
