Which of the following statements is true?
A . The dependent variable is represented on the x-axis.
B . The independent variable is also know as the output.
C . The dependent variable is represented in the 2nd column of a table.
D . The independent variable depends on the constant value.
my answer:
B
B is exactly the opposite of true. The output depends on the input.
Try C. Usually when making a table, you list the values of the independent variable, and then figure out the dependent values in column 2.
That is incorrect. The correct statement is:
C. The dependent variable is represented in the 2nd column of a table.
To determine which of the statements is true, let's analyze each statement one by one:
A. The dependent variable is represented on the x-axis.
This statement is incorrect. In a graph, the independent variable is represented on the x-axis, while the dependent variable is represented on the y-axis. The independent variable is the one being manipulated or controlled, while the dependent variable is the one being measured or observed.
B. The independent variable is also known as the output.
This statement is incorrect. The independent variable is not the output; it is the variable that is being manipulated or controlled to observe its effect on the dependent variable. The output, on the other hand, is usually the dependent variable, which is the variable being measured or observed.
C. The dependent variable is represented in the 2nd column of a table.
This statement is not necessarily true. In a table, the order of the variables can vary depending on how the data is organized. The dependent variable can appear in any column, not necessarily the second column. The important aspect is that the dependent variable is recorded as the response or outcome of the independent variable.
D. The independent variable depends on the constant value.
This statement is incorrect. The independent variable is not determined by a constant value. It is intentionally varied or controlled by the experimenter to observe its impact on the dependent variable. The constant value, also known as a control variable, is a variable that is held constant during an experiment to ensure that any observed changes are due to the independent variable and not other factors.
Based on the analysis above, none of the given statements are true. Therefore, none of the options are correct.
