Final answer:
The independent variable is sleeping after learning, and the dependent variable is memory for the poem.
Step-by-step explanation:
The independent variable in this experiment is sleeping after learning the poem, and the dependent variable is memory for the poem. The independent variable is the factor that the researcher manipulates or changes, while the dependent variable is the factor that is measured or observed to determine the effect of the independent variable.
For example, if a group of students is divided into two groups, with one group sleeping after learning the poem and the other group not sleeping, and their memory for the poem is tested afterwards, the independent variable would be the sleep after learning, and the dependent variable would be the memory for the poem.
Therefore, the correct answer is: Independent - Sleep after learning. Dependent - Memory of poem.
