Answer :
In summary, option B (Downhill ski performance (time taken to ski down hill)) is the correct answer.
In the given scenario, the dependent variable is downhill ski performance (time taken to ski down the hill).
Explanation:A dependent variable is the factor measured or affected by the researcher under controlled conditions during an experiment.
It is what the scientist measures in the course of the experiment. It is an event that is measured in response to the independent variable.
Here, the researcher is interested in determining the effect of tinted goggles on downhill ski performance.
Therefore, the time taken by 20 skiers on the downhill ski run is the dependent variable.
The independent variable is a variable that can be changed, and it causes another variable to change.
In this case, the independent variable is the type of goggles worn (brown, blue, red).
The dependent variable (Downhill ski performance) is the time taken to ski down the hill, which is measured in response to the different types of goggles worn by the skiers.
In summary, option B (Downhill ski performance (time taken to ski down hill)) is the correct answer.

The dependent variable in the study on the effect of tinted goggles on downhill ski performance is the time taken to ski downhill, which is the measure of ski performance.
In the context of the research question regarding the effect of tinted goggles on downhill ski performance, the dependent variable is B. downhill ski performance (time taken to ski down hill). This is because the dependent variable is what the researcher measures and is interested in seeing how it is affected by the manipulation of the independent variable, which in this case is the type of goggles worn (brown, blue, red).
Therefore, we can say that the time taken to ski downhill, which is the performance measure, is what changes in response to the type of goggles, making it the dependent variable.
