Lesson 1
Research
Descriptive research
Like Naturalistic observation to see patterns in the real world
Case study
Focus on a single case to suggest ideas for further research
Anecdotal evidence is not science
Surveys
Inexpensive assessment of beliefs
Wording should be carefully done for quality results
Loaded, biased, or ambiguous words skew results
Correlational research
Study that measures relationships between variables that are not manipulated
Like income and IQ score
correlation coefficient = r where r=0 is weak and r=1 is perfect correlation
Correlation and cause r not the same
Experimental Research
Study the effect of the independent variable by isolating it
Dependent variable represents results and performance
Experimental group is the one getting the treatment
Control is the normal group
Confounding variables skew the results the independent variable would've caused
Double blind design is a study where no one knows who is getting the treatment
Understanding population sampling
Random sample
A sample to represent the population
Population
Everyone in the study
Sample
A smaller representative group from the population
Ethics
