Pregunta 4
Pregunta
A hypothesis is a [blank_start]prediction[blank_end] that can be tested experimentally. It should state what effect you think changing the [blank_start]independent variable[blank_end] will have on the [blank_start]dependant variable[blank_end]. Must be written in [blank_start]third[blank_end] person.
