Exam 11: Other Ways That Statistical Analyses Contribute to Evidence-Based Practice

What types of statistical analysis are most likely to occur in a formative evaluation?

The theory underlying the two standard deviation methods for analysis of single system data relies on:

In social work meta-analysis, the independent variable is always:

In what type of program evaluation would a researcher be most likely to use inferential statistical analyses?

Why are parametric tests generally considered inappropriate for statistical analysis of meta- analysis data?

In social work meta-analysis, statistical analysis is used to learn if a method or type of intervention can be considered effective in addressing some problem. In meta-analysis, a research sample is comprised of a group of:

A commonly used form of statistical analysis in meta-analysis is:

What generally has to be done before data collected using qualitative methods can be statistically analyzed?

In an outcome evaluation, Hottelling's T² might be an appropriate statistical test to use if:

In another outcome evaluation, a researcher wishes to use statistical analysis to learn if a new program produced more reduction in a problem than the program used in the past. What is his dependent variable?

Parametric statistical tests generally are considered inappropriate for analysis of single system research designs because:

In single system research, research samples consist of:

In a program evaluation, qualitative data such as audiotapes of personal interviews must be analyzed. A first step is often to eliminate "noise" prior to transcribing them. To what does the term "noise" generally refer?

In analyzing single system data, which statistical test would be appropriate to use if the dependent variable is dichotomous and nominal level (e.g., medication compliance/non- compliance) and the client is in compliance only 30 percent of days during a four week baseline (A) phase?

In an outcome evaluation, a researcher decides to use two sample independent t to learn whether clients in a program showed more reduction in a problem than those in a randomly selected control group. What is her dichotomous independent variable?
