Social Work 671 Class # 1 Introduction & Review

Outline Introductions Why are we here? Syllabus Review Descriptive Statistics

Why have Social Work Research Classes Need to generate field specific information Need to test and document promising practices delivered practitioners are busy) Need to remain current on emerging practices (APA & NASW Journals assume readers know research methods) Need to meet external standards  University  CSWE

Syllabus Available on-line Ask questions (half the class likely has the same question) Review dates Review content

Review Problem Formulation Deductive versus Inductive Reasoning Operational Definitions Measurement Levels: nominal, ordinal, interval, ratio Probability Sampling: random, stratified, cluster, systematic

Review (continued) Descriptive Statistics Central Tendency Measures of Dispersion Experimental, Quasi-experimental, and Non-experimental Designs Qualitative and Quantitative Research

Descriptive Statistics Measures of Central Tendency  mean  median  trimmed mean  mode

Descriptive Statistics Measures of Dispersion  range  variance  standard deviation
