Question

teacher age vs. height
she wants to see if a teachers height depends on his or her age. what did she do wrong when she created the scatterplot?
she mixed up the independent and dependent variables.
she mixed up the x - and y - coordinates of the point representing teacher 3.
she plotted the point (36, 62) when she shouldnt have.
she labeled the x - axis of the scatterplot \age\ when she should have labeled it \teacher.\

Explanation:

In a scatter - plot, the independent variable is plotted on the \(x\) - axis and the dependent variable on the \(y\) - axis. Here, height depends on age. So, age is the independent variable (should be on \(x\) - axis) and height is the dependent variable (should be on \(y\) - axis). But in the given plot, the axes are labeled correctly. However, when we consider the general concept of scatter - plots for a relationship \(y = f(x)\) (where \(y\) depends on \(x\)), if we want to see if height (\(y\)) depends on age (\(x\)), the independent variable is age and the dependent variable is height.

Answer:

She mixed up the independent and dependent variables.
