Process of validating a survey
In order to perform data coding, read through the responses and group them into categories.
For instance, responses that are related to customer service can be coded under the category “Customer Service”.
Data coding simply means converting the nominal and ordinal scale data in such a way that the statistical package to be used can handle the survey data accurately.
This step is actually performed when you design the questionnaire, but the data codes become helpful during data analysis.
Please note that this is not an exhaustive list of assessments; other tools may be available that are not listed here.
This table lists specific tools that can be used either to assess a broad range of complex trauma domains or tap into a specific domain in greater detail.
On the other hand, it is best to use advanced statistical procedures such as Spearman’s rank correlation and Kendall’s tau to determine the relationship among the ordinal scale variables.The instruments provided here are designed for primary data collection and were selected for applicability to groups the NIH has termed "special populations", under-represented in patient-oriented research. The Network on Socioeconomic Status and Health has enhanced understanding of the mechanisms by which socioeconomic factors affect the health of individuals and their communities. This is the best paper I have seen directly comparing different ways of assessing healthcare discrimination, but it unfortunately doesn’t have a specific conclusion about which is best to use overall. The aim is to encourage inclusion of a broader range of human subjects in studies at UCSF and beyond. The Network’s research agenda established in 1997 has stimulated additional research in diverse fields, has contributed data to discussions of economic and social policy, and has provided a basis for social and medical interventions to foster better health among individuals and communities. Handling nominal data usually includes identifying the percentage of responses per category.Chi-square tests and multi-way tables are commonly used to measure the relationship between nominal scale variables.
