Research Methods & Stats Flashcards
This kind of variable affects the direction and/or strength of the relationship between independent and dependent variables
moderator
This kind of variable explains the relationship between independent and dependent variables
mediaator
These are not intentional parts of a research study, but affect the relationship between the study’s independent and dependent variables and make it difficult to determine if an apparent effect on an independent variable on a dependent variable is actually due to the independent variable
extraneous variables
Variables divide people into unordered categories
nominal
variables divide people into categories that are ordered in terms of magnitude
ordinal
Think ranks 1st, 2nd, 3rd, etc
Variables measured assign people to ordered categories with the difference between adjacent categories being equal
Interval
Exp: IQ scores. Even if someone got a score of 0 that doesn’t mean they have zero intelligence. There is no absolute zero.
Variables assign people to ordered categories with the difference between adjacent categories being equal and the scale having an absolute zero point
Ratio
Think weight, yearly income
These graphs are used for nominal and ordinal data
bar graphs
nominal and ordinal data listed on x axis; numbers or percentages on y axis
These graphs are used for interval and ratio data
histograms
scores listed on x axis and numbers or percentages listed on y axis
Line graphs are also called
frequency polygons
used for interval and ratio data
In a negatively skewed distribution what has the highest value
mode has highest value
median has middle and mean has lowest
In a positively skewed distribution what has the highest value
the mean
median has middle value and mode has the lowest
The primary goal of this type of research is to derive a general, abstract theory of a process, action, or interaction based on the views of participants.
What is the primary data collection method?
Grounded Theory ; interviews and observation
The purpose of this research is to gain an in-depth understanding of the “lived experience” of participants. What is the primary source of information?
Phenomenology ; In-depth interviews
This kind of research involves studying participants in their natural culture or setting in their naturally occurring activities. What is the primary data collection method?
Ethnography ; participant observation
This is a method of identifying, analyzing, and reporting patterns (themes) within data. It is a standalone method but can be a starting point for other method. What is the primary data method?
Thematic analysis ; in depth interviews and focus groups
