Manipulating a variable or two & observing the effects on another variable or two
Advantages of Experiments
-Cause & Effect Relationship -Gives you control over the environment you bring the experiment into
Limitations of Experiments
-People can act differently in labs -No external validity -Might not be accurate outside the lab
Involves collecting information from a large group of people on a large group of topics
Advantages of Surveys
-Studies how people perceive their worlds -Larger samples(compared to experiments)
Limitations of Surveys
People can LIE 1)to mess with you 2) to try and get what you want to hear 3)try and make themselves look good
Available Data
Looking at things that already exist
Advantages of Available Data
-Non-reactive -Don't have to rely on someone's memory -Great way to study the past
Limitations of Available Data
Sometimes the data does not exist
Field Research
Observing someone's behavior/communication in the natural setting
Advantages of Field Research
-Watching it in real time(no lying) -Lets you study things you can't stimulate in a lab
Limitations of Field Research
-NO Control -Need the ability to be observant in a non-bias way
Unit of Analysis
Individuals Dyads Groups Organizations
Independent Variable
Think Predictor -Impact on others -Cause (only in an experiment)
Dependent Variable
Think Outcome -being influenced/being impacted -Effect (only in an experiment)
Intervening Variable
In Between predictor & outcomes/independent & dependent
Control Variables
variables researchers want to be held constant throughout the duration on the study
Qualitative Variables
Think Type -Looking at different categories
Quantitative Variables
Think amount/numbers -Always counting & comparing
Shape of the Relationsip
Positive Relationship: Variables move in the SAME direction Negative Relationship: Variables more in the OPPOSITE direction Curvilinear Relationship: Relationship between variables MOVE from one point to another Independent: NO relationship
Strength of the Relationship: Correlation Coefficient
Further from 0 in either direction (+ or -) = STRONGER
Strength of the Relationship: Genetic Criteria for Social Sciences
.50(-.50)= STRONG relationship .30(-.30)= MODERATE relationship .10(-.10)= SMALL relationship
Brief summary of the study
Statement of the problem, information we don't have but need
