BY THE NUMBERS: QUANTITATIVE DATA ANALYSIS Sheika Kendi Georgia State University

Macalester College “Quantitative methods are distinguished by their emphasis on numbers, measurement, experimental design, and statistical analysis. Researchers typically work with a small number of predetermined response categories to capture various experiences and perspectives of individuals. Often emphasis is on analyzing a large number of cases using carefully constructed instruments that have been evaluated for their reliability and validity” (Patton, 1990). Techniques include questionnaires, structured interviews, and tests.” (Palomba and Banta, p. 337)

WHY USE QUANTITATIVE METHODOLOGY Ease of Data Collection Paper/Pencil Administration Web-based Survey Software

WHY USE QUANTITATIVE METHODOLOGY Ease of Data Analysis Less Time Consuming Process Easier to Train Staff Software Access (Excel Analysis ToolPak - descriptive statistics, histogram, correlation, t-test, ANOVA, regression, random number generation, etc.)

WHY USE QUANTITATIVE METHODOLOGY Large Number of Students Generalizablity of Findings

WHY USE QUANTITATIVE METHODOLOGY Combining Indirect and Direct Data Indirect data – Student perceptions, attitudes, skills, and knowledge Direct data – GPA, major, ethnicity/race, class standing, gender, program participation, etc.

HOW TO USE QUANTITATIVE METHODOLOGY Random Samples - representative Random Assignment - bias

HOW TO USE QUANTITATIVE METHODOLOGY Reliability and Validity of an Instrument Reliability – measure of consistency Construct/Face Validity – measure of instrument’s ability to operationalize program theory

HOW TO USE QUANTITATIVE METHODOLOGY Reliability and Validity of an Instrument Program Theory – In Evaluation: A systematic approach, Rossi, Lispey, and Freeman defined program theory to be the “plan of operation, the logic that connects [program] activities to the intended outcomes, and the rationale for why [a program] does what it does” (2004, p. 44).
