Research Methods Flashcards
What are and which are the research methods?
- Naturalistic Observation
- Case Study
- Survey
- Correlation Studies
- Experiments
- Quasi - Experiments
What is the naturalization observation ?
Observes without interfering, observes the behavior that was absorb.
DO NOT MAKE CONCLUSIONS
Quasi means
They are exposed
What is the Naturalistic Observation about?
Is about observing an animal or a human without interfering. It describes the behavior that was absorb
What are the advantages and disadvantages of the Naturalistic Observation Method?
Advantages: Provides descriptive data
Disadvantages: Can’t draw conclusions from observation. And participant may act in atypical ways.
What is the Case Study Method?
Deeply internal and external investigation of the behavior and mental processes of a rare,new or complex of a one or a few subjects.
What are the advantages and disadvantages of the Case Study Method?
Advantages: Provides a detail analysis is f the first individual
Disadvantages: Is not generalizable, is a about the researcher perspective
What is the Survey Research Method?
Questionnaire about “Common” attitudes, opinions, behaviors of a target population
What is validity?
Extent to which the survey measure what it claims to measure.
What is reliability?
The extent to which results can be repeated or replicated.
What are the advantages and disadvantages of the Survey Research Method?
Advantages: Takes a lot of data
Disadvantages: Social- desirability effect ( answer ways that we believe are social acceptable)
How do you get the Representative sample from a target population?
From the target population we do a random selection to select a representative sample (which represents the target population) to generalize the population,
What is the random selection?
Is the procedure we use so everyone in target population has an equal chance of being in sample. (Minimize sampling bias)
What is the Correlational Study Method?
Correlation means the association between 2 variables.
.
CORRELATION IS NOT CAUSATION
What is the Correlation Coefficient?
Descriptive statistics that tell us 3 factor about correlation.
0–> No correlation
+1 and -1 –> Perfect Correlation
What is a Statistical Significance?
Not a chance. ( No fue casualidad) the significancy that is very likely to do not happened by chance
What are the 3 factors about the correlation?
- Is there a relationship between the 2 variables?
If No: 0 and not statistically significant
If yes: Statistically significant and +-1 - How strong is the relationship?
Absolute Value - How do the variable relate?
Look for the sign +[] {} -[{ ]}
What are the advantages and disadvantages of the correlation studies method?
Advantages: examines 3 factors of the correlational coeficient, shows the strength of the correlation
Disadvantages: it gets confuse with cause and effect
What is the Experimental Research Method?
Is the study that manipulates one variable and the effect it produces on another variable.
Cause and Effect relationships.
What is the independent variable?
The manipulated variable (causal)
What is the experimental group?
Are the group of subjects that are exposed to independent and dependent variable.
( es manipulado y medido)
What is a control group?
Are the group of subjects that receive no exposure to the Independent Variable,but do receive dependent variable measurement
What is a dependent variable?
Measure variable “effect variable”
What is a confounding variable ?
Are any variables that in addition to or instead of the Independent Variable that affects the Dependent Variable measurement
What is a quasi experimental method?
When it is unethical to give the Independent Variables, which the experimental group is people that are volunteers
What is a hypothesis?
Is a testable statement which expose the effects of an IV on prediction from prior research. DV in a target population (including qualifiers)
