A student did an experiment to determine the number of letters recognized on an eye chart to see if it was affected by distance. What is the independent and dependent variable in this experiment?

Independent variable: distance

Dependent variable: number of letters recognized on an eye chart

Step-by-step explanation:

Independent variables are stand-alone. This means that it does not depend on another variable but affects the dependent variable.

Dependent variables are dependent on another variable. When the independent variable changes, dependent variables are changed.

Since the hypothesis is that the distance affects the number of letters recognized,

the distance causes a change in the number of letters recognized not the other way around.

Thus, the dependent variable is the number of letters recognized on the eye chart while the independent variable is the distance.
