Week 7-8: non experimental research, complex designs Flashcards
What’s archival research and another name for it ? (old.. to learn..)
Can be called secondary research as someone other than the researcher is collecting it. Archival research is old research we use to learn something new
What’s the difference between meta analysis and thematic analysis? ( running many .. sum..) ( make sense of.. unrel… by analyzing what? to gain in..)
Meta analysis: Taking many studys and running tests/stats on them to summate them together as one
Thematic anaylsis: Make sense of seemingly unrelated material by analyzing qualitative data to gain info/insight on collected data
What’s the cohort effect? (different res..)
Different researchers get different summations
Why doesn’t Elliott like thematic analysis? (i’m not a published author, is it valid?, where are u getting info from?) (3 things)
Need published co author first time if not published author
Not subject to rigorous scholar documentation
Ethically harder, very risky as you need quotes from ppls storys
What are focus groups how many ppl do they usually have how long are they and what’s their advantages and disadvantages? (groups of ppl discuss..) adv: reveal.. and gain., fast, genuine.. (3 things for advantages) disadvantages: trained..,money, wrong..
Focus groups are group interviews to explore what consumers want in a product/thing and what they think about it already. about 8-12 people per group 1.5-2.5 hrs long and recorded
Advantages: reveal and gain insight of perceptions, faster than single interviews, provides genuine group discussion and in-depth answers
Disadvantages: need trained moderater,expensive, can be wrong or misleading information
What’s triangulation? (how they correlate)
Putting 3 pieces of information/articles together to see how they correlate
What is regression? (predictor variables, outcomes)
Predictor variables trying to predict the outcomes variables
What is total variability?
Variability between scores and the mean
Why are complex designs necessary? (3 things- effect two things, determine .., measure diff..
To control for things taht could affect IV or DV
to determine obscure details
To measure different variables
What is a moderator variable it’s criteria and what does it affect?(interferes with.., and effects s and d.. must NOT BE a…)
A moderater variable is things that interfere with the relationship between IV and DV so it AFFECTS the strength and direction of relationship
IT MUST NOT BE A CAUSAL RESULT OF IV
What is a mediator and it’s criteria and function?
Mediated is the way IV impacts the DV and explains the process in which the two variables relate.
MUST BE CAUSAL RESULT OF IV AND CAUSAL EVENT OF THE DV
What’s the file drawer problem? (pub bias.., positive results than..)
type of publication bias, more likely to submit positive results than negative to publishers
What are 4 types of correlation and are they parametric or non parametric??
- Pearson -parametric
- Spearmen-non parametric
- Partial correlation-parametric
- Kendall’s-tau-non parametric
What can the 4 correlations do or have? (ties,scales,variance,changes)
Kendall’s-tau: can have many ties
Spearmen- can do correlation between likerd scales
Partial correlation- sees variance of multiple variables by isolating variance then taking out to see other variances
Pearson-changes in direction
What are the three types of t test and what do they measure? ( WS, BS, SS/D)
Within subjects t test- measures two time points making it repeated measures
Between subjects t test- measuring groups once, usually 2 groups a couple factors
Single sample/difference t test: measures to see difference between two things can be time points, knowledge
