A researcher was interested in finding out whether talking to plants was related to plant growth. To test this idea she used 20 plants where all 20 plants had the same amount of food, water and sunlight. She randomly assigned the 20 plants to 1 of 2 groups: she talked to 10 of the plants for 1 minute/day; she talked to the other 10 plants 10 minutes/day. Every day for one month the researcher measured the height of the plants. What is the Independent variable and the Dependent variable in the example above?

Mina is testing different types of heat lamps to determine which type is most effective for growing strawberry bushes. She purchases two different types of lamps from a local store. Mina applies brand A to one area of the yard and brand B to another area of the yard, both of which receive full sunlight. She waters the area with brand B daily; she waters the area with brand A every other day. At the end of the study, Mina concludes brand B is more effective in growing strawberry bushes. Mina's conclusion valid? Explain why or why not.
