Dependent Variable
variable that may change in response to an independent variable (dependent on the independent variable), being measured
Ex. rate of respiration
Extraneous Variables:
factors that affect the DV, that are not the IV
Ex. some expired yeast
Control Group
Group not exposed to IV
Ex. yeast in room temperature
Experimental Group
Group exposed to IV
Ex. some yeast exposed to lower temperatures, some exposed to higher temperatures
Random Assignment
Assigning participants to experimental and control conditions by random assignment
Attrition
reduction in the number of participants due to dropouts
Research Methods:
Observing and measuring variables without manipulating them
Naturalistic Observation
involves the careful observation and recording of behavior in real-life settings
Case Study
involves an in-depth study of an individual
Survey Method
the use of interviews and questionnaires in studying human behaviors
Correlational Method
the examination of the quantitative relationships between two or more variables
Longitudinal Research
Gathering data is administered repeatedly over an extended period of time
Cross-Sectional Research
Comparing of multiple segments of population at a time
Statistical Analysis
Watch Out For:
Illusory Correlations
When people believe a relationship exists between two things when it actually doesn’t
Placebo Effect
When people’s expectations/beliefs influence or determine their experience in a given situation
Analysis
Correlation
Scatterplots
Measures of central tendency
