Chapter 2: Research Methods Flashcards
what is the CRITICALLY THINKING PROCESS?
questions of cause & effect, quality, and value to be used to evaluate any claims
ways to apply CRITICAL THINKING?
-what are you being asked?
-is the evidence that is being presented valid?
-are there alternative ways to interpret evidence?
-what additional info do you need to interpret evidence?
describe the process of SCIENTIFIC METHOD
-observation
-hypothesis: a testable prediction
-operational definitions: turning concepts into something measurable
-collect data (sometimes this leads back to your observation)
-theory: set of statement
name some RESEARCH METHODS and their pros and cons?
-naturalistic observation: watching without intruding (p:natural behavior/c:can’t observe everything)
-case study: focus on one individual or situation (p:good in rare situations/c: may not generalize)
-survey: questionnaires or interviews (p:lots of answers/c:could be inaccurate)
-correlational studies: how 2+ variables are related (correlation)
types of VARIABLES in experiments?
-dependent: what is expected to change
-independent: what we change
what is an EXPERIMENT?
we change one variable to see what happens to other variables
what is the importance having REPRESENTATIVE SAMPLING?
participants of the sample reflect characteristics of the population
difference between MEAN, MEDIAN, and MODE?
mean: average of sample
median: middle value
mode: most common value
Causation doesn’t equal…
Correlation
if the correlation= -0.94, this means that…
there is a strong, inverse relationship between the two variables
