Identify the 3 types of hypothesis.
nondirectional
directional
simple

What are nondirectional, directional, simple
The three parts of the methods section
participants

design
framework
What are participants, procedures, and design?
The dependent variable is that which is under investigation.
True
False
True. The dependent variable is that which is under investigation.
A good hypothesis must:
A. Be proven by empirical data.
B. Serve as a guide for descriptive research.
C. Identify predicted outcomes of the study.
D. State several relationships among variables
What is Identify predicted outcomes of the study.
Regardless of the specific format used to state a hypothesis, the statement includes the variables being studied, the population being studied, and the predicted outcomes.
The two descriptive words of an alternative hypothesis
What are directional and nondirectional?
Something important to include in the section of the written explanations of study findings
restating the study's hypothesis
restating the study's PICO
restating the study conclusions
restating the study methodology
What is restating the hypothesis or research questions?
What are the three types of variables
dependent
extraneous
extemporaneous
independent
numerator
What is extraneous, independent, and dependent?
the independent variable is manipulated to determine effect it has on another variable.
The dependent variable is observed for change after the treatment is applied
Extraneous variable is a characteristic not under investigation but may be relevant to the study

PICOT
What are dependent and independent variables?
