Research Material 1-4 Flashcards
Scientific method
an organized series of steps that ensure maximum objectivity and consistency
hypothesis
a statement about the expected relationship between or among observable measures of concepts
a hypothesis is NOT
a guess or a hunch- it is based on review of other studies
a hypothesis compares
2 or more factors called variables
variables
measurable trait or characteristic that is subject to change under different conditions (age, gender)
a variable must
change, vary, can take more than one value
independent variables
associated with causes. (causes predicts another variable)
dependent variables
associated with consequences. (its action depends on the influence of the independent variable)
validity
the degree to which a measure truly reflects the phenomenon under study
reliability
the extent to which a measure provides consistent results
quantitative research
“quantity” something you can count numerically to measure (using scientific method and statistics)
qualitative research
“quality” uses “thick description” in order to understand the insiders view of other human beings (using interview narrative)
mean
average score
median
middle score (helpful when data is skewed)
mode
most frequently appearing score
statistics show us
the probability that this occurred by random chance; weather or not results are meaningful
research process
theory construction, theory testing, and theory testing principles
theory construction
wonder, conceptualize, and theorize
