  1. ANALYSIS PLAN: STATISTICAL PROCEDURES Lu Ann Aday, Ph.D. The University of Texas School of Public Health

  2. DESCRIPTIVE STATISTICS Estimate for a sample EXISTENCE OF ASSOCIATION Statistically test the presence of a relationship INDEPENDENT SAMPLES Distinct or unrelated groups INFERENTIAL STATISTICS Infer to a population STRENGTH OF ASSOCIATION Statistically measure the strength of a relationship RELATED SAMPLES Matched or correlated groups TYPE OF ANALYSIS PROCEDURES: Alternative Assumptions

  3. PARAMETRIC PROCEDURES Random sampling Normal distribution > 30 cases Interval or ratio data NON-PARAMETRIC PROCEDURES Random or nonrandom sampling Normal or non-normal distribution < 30 or> 30 cases Nominal or ordinal data TYPE OF ANALYSIS PROCEDURES: Alternative Assumptions

  4. STUDY OBJECTIVES 1. TO DESCRIBE X, Y, or Z 2. TO COMPARE Y by X, or Z by X 3.TO TEST THE IMPACT/ANALYZE THE RELATIVE IMPORTANCE of X on Y [controlling for Z] (assumes Ho) TYPE OF ANALYSIS Univariate Bivariate Multivariate RELATE STUDY OBJECTIVES & TYPE OF ANALYSIS

  15. DATA ANALYSIS MATRIX

  16. STATISTICAL PROCEDURE SELECTION: SOFTWARE • SELECTING STATISTICS • You could access and use the “Selecting Statistics” website in deciding which statistical procedures are most appropriate, given your study objectives and associated level of measurement of study variables: http://www.socialresearchmethods.net/selstat/ssstart.htm

  17. SAMPLE MOCK & ANALYSIS TABLES • See Word file with Sample Mock Tables and Analysis Tables.

  18. SURVEY ERRORS: Planning and Implementing the Analysis of the Data
