QUESTIONS WITH ANSWERS GRADED A+
◉ critical thinking. Answer: My Definition: Not going with the
easiest answer, but examining how the answer was found. Looking
for variables, different sources of evidence, etc.
Example: Not believing everything you see on the internet. When
there is a heading, "Polar bears will be extinct in 2 years!" we need
to find the evidence to support that.
◉ theory. Answer: My Definition: A proposal that's been backed up
by research.
Example: Big Bang Theory
◉ hypothesis. Answer: My Definition: prediction that can be tested
Example: Teenage males are, on average, taller than teenage females.
◉ hypothesis testing. Answer: My Definition: Creating an
experiment to test the testable prediction
Example: To test dogs' favorite food brand, have a single dog with no
previous association to the brands tested in a room with two or
three bowls for the different kinds of brands. Which do they eat?
,◉ operational definition. Answer: My Definition: Specific definitions
of the variable being tested so it is both measurable and manageable
Example: Happiness (how many times participants smile)
◉ replication. Answer: My Definition: To do another experiment to
see if you get the same results. This will either hurt or strengthen
the theory.
Example: Mr. Rogers did an experiment at Southwestern University.
With the same control groups and variables but different
participants, Mrs. Shinge mimics the experiment at Northwest
University.
◉ case study. Answer: My Definition: Deeply involved examination of
people or situations with unique behavioral/mental processes.
Example: Patient H.M.
◉ survey. Answer: My Definition: Set of questions given to a
representative sample of the population to reflect on their attitudes,
opinions, and behaviors. You can receive a lot of information in a
short amount of time, but people might not be honest.
Example: Youth Risk Behavior Survey
◉ population. Answer: My Definition: Who you want to be able to
draw conclusions about.
, Example: If a survey is given to a group of GVHS teachers, it is to be
applied to the rest of GVHS teachers.
◉ random sample. Answer: My Definition: Sample that is
representative of the general population to be able to generalize
findings.
Example: Instead of picking only English teachers to survey, you
want to have teachers from all subjects. That way the findings can be
true for the whole school (and beyond).
◉ naturalistic observation. Answer: My Definition: Observing and
collecting data on behavior in natural situations. You are not trying
to manipulate or control.
Example: Dian Fossey and mountain gorillas (see picture)
◉ correlation. Answer: My Definition: Finding a relationship
between two variables
Example: The more gas in your tank, the more miles you can drive.
◉ correlation coefficient. Answer: My Definition: Number that
shows the strength of the correlation; from -1 to 1. The sign doesn't
deal with the strength of the correlation.
Example: If the more hours you sleep moderately and positively
correlates with memorizing ability, then the correlation coefficient
would be around +.60.
