KEY CONCEPTS AND ISSUES

Note: This listing is not intended to be exhaustive, but rather to help guide and focus your studying.

Overview of Survey Research

Strengths & weaknesses * key characteristics compared to field research and experimentation * guidelines for writing good questions * clarity and precision * appropriate vocabulary * double-barreled questions * emotionally loaded words * leading questions * agreement bias * negative items * position biases * sensitive questions * exhaustive and mutually exclusive response categories * respondent competency * format considerations * question placement * randomized response technique * self-administered questionnaire * mail questionnaire * interviewer administered questionnaires * face-to-face interviews * telephone interviews * probes * closed-ended questions * open-ended questions * response rates.

Sampling and Statistics

Probability sampling * non-probability sampling * target population * sampling frame * random sampling * parameter * statistic * simple random sampling * systematic random sampling * stratified random sampling (proportionate vs. disproportionate) * cluster sampling (single-stage vs. multistage) * primary sampling units * availability / convenience sampling * quota sampling * purposive / judgmental sampling * snowball sampling * systematic sampling error * random sampling error * descriptive statistics * inferential statistics * measures of central tendency: mean, median, mode * measures of spread / dispersion: variance, standard deviation * chi square test of independence * bivariate statistical tables * analysis of questionnaire data * variability * correlation matrix * internal consistency / inter-item reliability.

Experiments

Strengths & weaknesses * key features of a "true" experiment * random assignment vs. random sampling * internal validity (causal validity) * external validity * experimental group (treatment group) * comparison groups * control group * matching * pretest * posttest * threats to internal validity * selection bias * differential attrition * external events / history effects * endogenous change: maturation, testing effects, instrumentation, regression * contamination * other types of treatment misidentification (such as staff expectations, placebo effect, Hawthorne effect) * pre-experimental designs * one-shot case study * one-group pretest-posttest design * static-group comparison * "true" experimental designs * pretest-posttest control group design * posttest-only control group design * Solomon four-group design.

Evaluation Research

Purpose * distinctions between applied evaluation research and basic social research * measurement problems * important measurement issues to consider * threats to external validity * stakeholders * types of evaluation research designs.
