Question

1. which of these is an example of quantitative data? a) the plant is green b) the plant grew 5 centimeters c) the plant looks healthy d) the plant has shiny leaves 5. why do scientists retest their experiments? running the cycle over to find other outcomes 6. a student wants to see if plants grow taller when they are watered with soda instead of water. the student waters one plant with plain water and another plant with soda for two weeks. at the end, the student notices the soda plant looks brown and droopy, while the water plant looks green and healthy. the student also measures the height of both plants. write the prediction: __________ give one example of quantitative data: ________ give one example of qualitative data: __________

Explanation:

Quantitative data is numerical. "The plant grew 5 centimeters" is numerical, so it's quantitative. Scientists retest to confirm results and reduce errors. For the plant - soda experiment, a prediction could be plants watered with soda will grow less. Quantitative data is the height measurement. Qualitative data is the visual appearance like "the soda plant looks brown and droopy".

Answer:

1. B. The plant grew 5 centimeters
2. To confirm results and reduce errors
3. Prediction: Plants watered with soda will grow less or not as well as those watered with water.

Quantitative data: The height of the plants (e.g., the height of the water - plant or the soda - plant in centimeters).
Qualitative data: The soda plant looks brown and droopy; the water plant looks green and healthy.
