Question
Javier and his twin sister both have the same science exam. Javier sleeps for 9 hours the night before the exam, and his sister sleeps for 6 hours. After they take the test, they both compare their test grades. The dependent variable is ___________.
- The number of hours of sleep they had
- The type of test
- The test grades
- Javier
Hint:
In a given equation, the 2 variables viz. x & y can be bifurcated into Independent variable and dependent variable.
The independent variable can be referred to as the cause i.e. Its value is independent (does not change as per the other variables) of other variables. The dependent variable can be referred to as the effect. Its value depends on changes in the independent variable.
Generally, Independent variables are represented on the x-axis i.e. horizontal axis and Dependent variables are represented on the y-axis i.e. verticle axis.
The correct answer is: The test grades
GIVEN-
Number of hours of sleep Javier gets = 9 hours
Number of hours of sleep his sister gets = 6 hours
Test scores is compared at the end.
TO FIND-
Dependent variable in the given scenario.
SOLUTION-
In the given scenario, we observe that the test scores are compared at the end.
We know that number of hours they both sleep is a given criteria. i.e. it is the pre condition that is to be fulfilled at the beginning.
However, the test scores of both the twins will depend on the number of hours of sleep they both get.
Hence, "The test grades" is the Dependent variable in this situation.
FINAL ANSWER-
Option 'c' i.e. 'The test grades' is the correct answer to the given question.
