Likert-type Scales and Analysis

Elaine Allen and Christopher A. Seaman Surveys are consistently used to measure quality. For example, surveys might be used to gauge customer perception of product quality or quality performance in service delivery. Likert scales are a common ratings format for surveys. Statisticians have generally grouped data collected from these surveys into a hierarchy of four levels of measurement: Nominal data: The weakest level of measurement representing categories without numerical representation.

Data analyses using nominal, interval and ratio data are generally straightforward and transparent. An underlying reason for analyzing ordinal data as interval data might be the contention that parametric statistical tests (based on the central limit theorem) are more powerful than nonparametric alternatives.

Questionnaires from the National Health Interview Survey (NHIS) are available for viewing and/or downloading via the Internet as follows: For each NHIS data year from 1962 to 1996, one of the documents that was released was called "Current Estimates from the (National) Health Interview Survey".

These Current Estimates documents contained tables for each year's data. In addition, Appendix III in each Current Estimates document contains an image of most or all of the questionnaires used for that data year. The Current Estimate documents were released as part of the Series 10 group of documents from the National Center for Health Statistics (NCHS). The full list of Series 10 reports can be seen at the NHIS home page and, under the heading "Reports", click on "Vital and Health Statistics, Series 10 Reports (including Summary Statistics Reports)". Selected supplement questionnaires for the 1975-1983 period are shown in Appendix IV of Series 1, No, 18 [PDF - 12 MB]. [PDF - 12.6 MB]. YRBS Question Content 1991-2017. YRBS 2017 Item Rationale. Survey Standard Definitions. DEERFIELD, IL (April 20, 2015) – The American Association for Public Opinion Research (AAPOR) is pleased to announce the release of the Eighth Edition of the Standard Definitions - Final Dispositions of Case Codes and Outcome Rates for Surveys.

Survey Standard Definitions

For a long time, survey researchers have needed more comprehensive and reliable diagnostic tools to understand the components of total survey error. Some of those components, such as margin of sampling error, are relatively easily calculated and familiar to many who use survey research. Defining final disposition codes and calculating call outcome rates is the topic for this booklet. Often it is assumed — correctly or not — that the lower the response rate, the more question there is about the validity of the sample. With this report, AAPOR offers a new tool that can be used as a guide to one important aspect of a survey’s quality. AAPOR hopes to accomplish two major changes in survey research practices. Response Rates - An Overview. Summary: Calculating response rates - the number of eligible sample units that cooperate in a survey -- has historically been central to survey research in the United States because of the assumption that the larger the proportion of participating sample units, the more accurate the survey estimates.

Response Rates - An Overview

Formulas for calculating rates are now standardized, but the relationship between response rates and survey quality has become much less clear. Measuring Response Rates Until recently, there were almost as many ways to calculate response rates as there were researchers. Response rates, cooperation rates, and completion rates were often treated as interchangeable in the literature. Sample Size Calculator. Satisfaction Video.

What is Ethics in Research & Why is it Important?

When most people think of ethics (or morals), they think of rules for distinguishing between right and wrong, such as the Golden Rule ("Do unto others as you would have them do unto you"), a code of professional conduct like the Hippocratic Oath ("First of all, do no harm"), a religious creed like the Ten Commandments ("Thou Shalt not kill... "), or a wise aphorisms like the sayings of Confucius. This is the most common way of defining "ethics": norms for conduct that distinguish between acceptable and unacceptable behavior. Most people learn ethical norms at home, at school, in church, or in other social settings. Although most people acquire their sense of right and wrong during childhood, moral development occurs throughout life and human beings pass through different stages of growth as they mature.
