Dependent and Independent Variables

If y represents money earned and x represents A's on a report card, which is the dependent variable?

• x = A's on a report card

• y = money earned

• x and y are both dependent variables

• None of the above

What is an independent variable?

• A variable that is measured in an experiment.

• A variable that is kept constant throughout the experiment.

• A variable that is changed or controlled to test its effects on the dependent variable.

• A variable that does not affect the outcome of the experiment.

What is an example of an independent variable in a plant growth experiment?

• The type of soil used for planting.

• The amount of water each plant receives.

• The amount of sunlight each plant receives.

• The size of the pots used for planting.

What is the purpose of identifying independent and dependent variables in an experiment?

• To determine the sample size needed for the experiment.

• To understand the cause-and-effect relationship being studied.

• To ensure the experiment can be replicated by others.

• To identify potential sources of error in the experiment.

How can you identify the independent variable in a table of values?

• The independent variable is usually the output or effect, often found in the last column.

• The independent variable is usually the input or cause, often found in the first column.

• The independent variable is always a constant value throughout the table.

• The independent variable is typically represented by a graph rather than a table.

In the context of a batting cage, what is the independent variable when considering the total cost based on the number of tokens purchased?

• The total cost of tokens

• The number of tokens

• The price per token

• The duration of time spent in the cage

What does an open dot represent when graphing inequalities?

• It indicates that the value is included in the solution set.

• It represents a fixed value that cannot change.

• An open dot represents that the value is not included in the solution set, used with < or > symbols.

• It shows the maximum value of the inequality.

What is the relationship between independent and dependent variables?

• The independent variable is manipulated to observe its effect on the dependent variable.

• The dependent variable is manipulated to observe its effect on the independent variable.

• Both variables are always equal in value during an experiment.

• Independent variables do not affect dependent variables.

What is a dependent variable?

• A variable that is manipulated in an experiment.

• A variable that is measured and affected in an experiment, responding to changes in the independent variable.

• A constant that remains unchanged throughout the experiment.

• A variable that is not relevant to the experiment.

On which axis is the independent variable plotted on a graph?

• x-axis

• y-axis

• z-axis

• t-axis
