Surveys, Experiments, and Data: Tutorial

Carla is conducting an experiment to determine how effective her homemade plant food is. In her experiment, she randomly selects 24 sunflower seeds from a package and places six each in four different containers. She places all four containers next to each other on her deck so each container receives the same amount of sunlight, and she waters the containers every other day with the same amount of water.

For the next month, Carla applies her homemade plant food to three of the containers, as shown in the table. At the end of the month, Carla measures and records the average height of the sunflowers in each container.

To match the terms with the correct descriptions in the context of Carla's experiment, let's break down the scenario step by step. Here's a detailed explanation:

1. Experiment Setup: Carla sets up four containers, each containing six sunflower seeds. All containers are placed next to each other on the deck to receive equal sunlight and are watered with the same amount of water every other day.

2. Plant Food Application: Over the course of the next month, Carla applies different amounts of her homemade plant food to three of the containers. The fourth container does not receive any plant food and acts as a control group.

3. Recorded Data: At the end of the month, Carla measures the average height of the sunflowers in each container.

Now let's examine the plant food applied to each container:
- Container 1: Receives 1 teaspoon of plant food.
- Container 2: Receives 2 teaspoons of plant food.
- Container 3: Receives 3 teaspoons of plant food.
- Container 4: Receives 0 teaspoons of plant food.

Given this information, here is the matching of terms with their correct descriptions based on the context:

- Container 1: This container receives 1 teaspoon of plant food.
- Container 2: This container receives 2 teaspoons of plant food.
- Container 3: This container receives 3 teaspoons of plant food.
- Container 4: This container receives 0 teaspoons of plant food and serves as the control group.

Thus, the tiles can be matched as follows:
1. Container 1: 1 teaspoon of plant food.
2. Container 2: 2 teaspoons of plant food.
3. Container 3: 3 teaspoons of plant food.
4. Container 4: 0 teaspoons of plant food (control group).

By setting up her experiment in this manner, Carla is able to compare the growth of the sunflowers with varying amounts of plant food and determine its effectiveness. The control group (Container 4) allows her to see the effect of no plant food, providing a baseline for comparison.
