A research [blank_start]problem[blank_end] is an enigmatic or troubling condition.

A statement of [blank_start]purpose[blank_end] in a quantitative study states the research aim and indicates the key study variables and the population of interest.

A research [blank_start]question[blank_end] is what researchers wish to answer through a systematic study.

A [blank_start]hypothesis[blank_end] is the researcher's prediction about variables in the study.

Hypotheses predict a [blank_start]relationship[blank_end] between the independent and dependent variables.

Hypotheses are typically put to a statistical [blank_start]test[blank_end].

A hypothesis stipulates the expected relationship between an [blank_start]independent[blank_end] variable and a dependent variable.

A research hypothesis in which the specific nature of the predicted relationship is not stipulated is a [blank_start]nondirectional[blank_end] hypothesis.

The results of hypothesis testing never constitute [blank_start]proof[blank_end] that a hypothesis is or is not correct.

Hypothesis typically involve at least [blank_start]two[blank_end] variables.

A [blank_start]simple[blank_end] hypothesis involves a single independent and a single dependent variable.

The actual hypothesis of an investigator is the [blank_start]research[blank_end] hypothesis.

The hypothesis that posits the absence of a relationship between variables is called a [blank_start]null[blank_end] hypothesis.
