Answer:

Explanation:

An independent variable is the variable that is intentionally altered or changed during the course of an experiment and is not dependent on another variable. The independent variable from the narration in the question is the different types of plants (as seen, the type of plant was intentionally changed during the course of the experiment).

A dependent variable is the variable whose "outcome" is assumed/expected to be dependent on another variable called the independent variable. The dependent variable from the narration in the question is the number of flowers (as seen, the outcome/number of flowers is expected to be dependent on the type of plant).

The control group is the group that is used as a reference (or benchmark) for the sake of comparisons while reporting an experiment. From the narration in the question, nothing was mentioned as regards the control group.

Constants are unchanged factors that are maintained throughout the course of an experiment. From the narration, the constant is the time in which her observations are done which is weekly (every week).

  2. Dependent Variable (DV): Number of flowers
  3. Control Group: None
  4. Constants: Duration/time of recording

INDEPENDENT VARIABLE:

  • Independent variable is the variable that is changed or manipulated in an experiment in order to bring about a response.

DEPENDENT VARIABLE:

  • Dependent variable is the variable that is measured or recorded in an experiment.

CONTROL VARIABLE:

  • Control variable or constant is the variable that is kept unchanged throughout the experiment.

  • According to this question, a person conducts an experiment by counting the number of flowers she sees on different types of plants. She records data every week.

In this experiment;

  1. Independent Variable (IV) is the different types of plants because it was changed.
  2. Dependent Variable (DV) is the number of flowers because it is recorded.
  3. Control Group: None
  4. Constants: Duration/time of recording
