27. which is true about the response variable?

i. this used to be called the independent variable.
ii. when graphing the data, the response variable is plotted along the y-axis

only i
only ii
both i and ii
neither

it is one question stupid

Both i and ii are true about the response variable.

i. The response variable is used to be called the dependent variable, not the independent variable. The independent variable is the variable that is manipulated or controlled in an experiment.

ii. When graphing the data, the response variable is plotted along the y-axis. The y-axis represents the variable that is being measured or observed, which is typically the response variable.

To determine which statement is true about the response variable, we need to understand the concepts of independent and response variables, as well as how data is graphed.

I. The independent variable is the variable that is manipulated or controlled in an experiment. It is the variable that is presumed to have an effect on the response variable. The response variable, on the other hand, is the variable that is being measured or observed in an experiment. It is the variable that responds to changes in the independent variable.

II. When graphing data, the independent variable is typically plotted along the x-axis (horizontal axis), while the response variable is plotted along the y-axis (vertical axis). This allows us to visually analyze the relationship between the two variables.

Based on these definitions, we can evaluate the given statements:

i. This used to be called the independent variable.
- This statement is incorrect. The response variable is not the same as the independent variable. The response variable is what is being measured, while the independent variable is what is being manipulated.

ii. When graphing the data, the response variable is plotted along the y-axis.
- This statement is true. To display the relationship between the independent and response variables, the response variable is typically plotted on the y-axis.

Therefore, the answer is:
Both i and ii.
