Question

question 7 1 pts a researcher predicted that talking to plants enhances their growth. she gave 24 plants the same amount of water and sunlight. she talked to 12 of the 24 plants daily for 6 weeks and then measured their growth. in this experiment, which of the following is the dependent variable?
○ food, water, and sunlight
○ the plants
○ talking to the plants
○ growth of the plants

Explanation:

To determine the dependent variable, we recall that the dependent variable is the outcome being measured, which depends on the independent variable. In this experiment, the researcher manipulates "talking to the plants" (independent variable) and measures the "growth of the plants" to see the effect. "Food, water, and sunlight" are controlled variables, "the plants" are the subjects, and "talking to the plants" is the independent variable. So the dependent variable is the growth of the plants.

Answer:

D. Growth of the plants
