Question 6

As part of a larger investigation into the relationship between skin type and degree of redness when subjected to varying intensities of UV light, a researcher devised an experiment to determine the extent to which various types of skin turned red when subjected to the aforementioned conditions. The researcher began by classifying one hundred people into six distinct categories based on their skin type. Next, he subjected these individuals to progressively higher doses of UV light and monitored the degree to which their skin became reddened.
In this experiment, which variable is considered to be an independent variable and which is considered to be a dependent variable?

Accepted Answer

An independent variable is the skin type; a dependent variable is the redness.

Answer

An independent variable is the amount of UV light; a dependent variable is the skin type.

Answer

An independent variable is the skin type; a dependent variable is the amount of UV light.

Answer

An independent variable is the redness; a dependent variable is the amount of UV light.
