Question

I could buy 6 sunflower seeds and 6 flower pots from grocery outlet. Planting 3 sunflower seeds in 3 pots of soil, and planting the other 3 sunflower seeds in 3 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 experimental design is well thought out! Let's clarify the components of your experiment based on your descriptions:

### Treatments
- **Treatment**: The type of growing medium (soil vs. sand) in which the sunflower seeds are planted.

### Response Variable
- **Response Variable**: The height of the sunflower plants, which measures the amount of plant growth.

### Random Selection
- **Random Selection**: This would refer to the process of choosing the sunflower seeds from the source (such as a store or nursery). This ensures that the seeds you select are representative of the population of sunflower seeds available.

### Random Assignment
- **Random Assignment**: This happens when you assign the selected sunflower seeds to the treatment groups (soil or sand). For example, you could randomly assign 3 seeds to be planted in soil and 3 seeds to be planted in sand. This helps control for variability and ensures that any difference in plant height can be attributed to the type of growing medium.

This structured approach allows you to effectively test the impact of the type of growing medium on sunflower growth while controlling for other variables. Good luck with your experiment!
