Document Summary

Large samples are more likely to be representative than smaller sample survey: volunteer bias: people might have stronger opinions on the topic of the survey, wording: how question is worded can impact the results. Research methods: correlational research: linear relationship between two variables, correlational analysis: statistical procedure that provides a mathematical estimate to the extent of which two variables are linearly related to each other, often done on data gathered from surveys. Independent variable: manipulated: dependent variable: measured, groups, experimental group: exposed to the factor of interest/manipulation of independent variable, control group: not exposed to manipulation of independent variable, treated the same in all other way. Research issues: variables must be operationally defined, operational definition: a precise definition, confounding variables: uncontrolled factors that may influence the dependent variable, confuses interpretation. Statistical significance: mathematical estimation of how likely experimental results are due to chance: how likely is it that the average difference between the experimental and control groups on the.
