A variable that influences another variable is called?

Independent Variable

What is Qualitative ?

-Focuses on emotions (abstract)
"Do you feel happy?"

What is Quantitative?

-Focuses on Numbers

What is Random Error?

-Can be because of complex measurement systems or professional jargon, lost in translation




-Data entry mistakes, someone not understanding vocabulary words

What is an Independent Variable?

-IMPACTS cause, does NOT depend on another variable

What is an Dependent Variable?

-OUTCOME Effect, Dependent relies on the independent for a possible change

What are the threats to internal validity?

-History
Outside events effecting the group




-Maturation
Natural growth between testing




-Testing
Repeated measures effect score




-Instrumentation Change
Changes effect results




-Statistical Regression
At risk for outliers




-Selection Bias
'Cherry Picking'




-Ambiguity
Not sure on the direction of which causes which



Draw and explain a ONE SHOT case study

X
O




-Fails to control for any of the threats of internal validity
-Give the intervention, observe the results

Characteristics of a good research question

-Not easily answered
-Can be repeated
-Has more than one answer
-It should lead to new information
-Specific
-Clear and concise

What is the relationship where both the variable increases or decreases ?

-Positive

What is the relationship where one variable increases while the other decreases?

Negative/inverse

What is bottom-up?

-Own Research

What is top-down?

-Using stuff that has already been researched

What does an IRB (Institutional Review Board) do?

-Reviews research studies to ensure they are ethical
-Protect the subjects rights and interests and ensure that the risks they face by participating are minimal and justified by the expected benefits of the research

What is a control group?

-Does NOT get the intervention

What is a experimental group?

-Does get the intervention

What is the criteria for conferring causality?

1. Independent variable comes first (IV BEFORE DV)
2. Two variables go together (IV & DV)
3. Not better explained by a third variable

What is internal validity?

-How confident the intervention is causing the change

Inductive Reasoning

-Observation leads to the theory
EX: I went to a classroom in an elementary school to observe and determine whether girls or boys have higher self esteem

(Observation - Pattern - Tentative Hypothesis - Theory)

Deductive Reasoning

-Start with a theory that you want to test

(Theory - Tentative Hypothesis - Pattern - Observation)

What is statistical regression?

-Threat, regress it with data

Systematic Error

-Problem with the system or instrument

Likert Scale

A five (or seven) point scale which is used to allow the individual to express how much they agree or disagree with a particular statement.

Experimental Designs

-What you do before an experimental study

-One shot case study
-Pre test post-test with one group
-Post test only with nonequivalent groups

Pre-test post-test with one group

O1 X O2

Post-test only with nonequivalent groups

X O


O

Experimental Designs

-Has random selection, at least two groups

-Pretest Posttest with control group
-Posttest only with control group
-Solomon 4 group design
-Dismantling
-Alternative treatment studies

Pretest Posttest with control group

R O1 X O2
R O1 O2

Posttest only with control group

R X O
R O

Solomon 4 Group Design

R O1 X 02
R O1 O2
R X O2
R O2

Dismantling

R O1 XAB O2
R O1 XA O2
R O1 XB O2
R O1 O2

Alternative Treatment Studies

R O1 XA O2
R O1 XB O2
R O1 O2

Curvilinear Relationship between IV and DV

-Effect goes one way, stays steady and eventually goes the other way

-Relationship changes/curves over time

Cross sectional study

-Analyzes data from a specific point in time

Longitudinal Study

-Data is repeatedly covered over an extended period of time

Acquiescence Set Bias

When you have a test and the participant responds to questions based on a pattern




Acquiescence = agree (say 'yes' for each question)

Systematic Error

Scale is measured wrong, affects everything

Social Desirability Bias

-Getting an answer to a question that is socially acceptable to a survey

(All want to look good, getting the right answer)

What to include on Informed Consent

-Purpose
-Risk
-Contact Information
-Benefits
-Alternative treatments
-What the study is
-Referral
-Procedures of the study
-How researchers would manage confidentiality
-Ask the participant to agree (voluntary)
-Participant is allowed to withdraw
-Minors (get consent from parent/guardian

Validity

-The response is accurate
