The Road to Successful Research Requires
Measurement Validity and Reliability
"I think a lot of parents trusted the school system that they would have a plan in place, and quite obviously they did not," Angie Franks told CNN on Monday." Who We Are We are a group of statisticians focused on improving data and study validity and reliability. We work with audit groups, survey specialists and people doing research. Our president is Dr. John M. Ryan Ph.D. in Research and Statistical Methodology. Dr. Ryan has worked internationally with private manufacturing clients and with governmental agencies. He has published a number of technical books and over 100 articles. He specializes in the validit/reliability field and provides training via live webinars. We are located in Las Vegas, Nevada.
Uncounted Millions have Covid but no positive test
The COVID tests and the entire testing process must be as valid and reliable as possible and it is the governments responsibility to assure that this happens.
Why You need Validity and Reliability for your data, survey or study findings
But many of these companies have never formally and statistically analyzed either their audit or survey instrument data, processes or the data available from their auditors from a validity and reliability perspective.
Validity and reliability analysis of these data sets and the audit processes can help focus their audits to reduce the time and money spent collecting the data while simultaneously attaining defendable and improved accuracy of the domains they believe they are studying and the reduce the variablity of humans actually collecting the data, the field auditors.
Example Number 2The government wants to develop an overall integrated food safety system that measures food safety from the federal, srate and local levels. However, all three levels of government use hundreds of different audit standards, different audit questions and different methods to collect the data. The feds want a nation-wide farm-to-fork food safety measure as required by congress but the data coming from hundreds of independent federal, state and city audits and thousands of auditors are incompatable.
A validity and reliability study of all three governmental food safety audit levels can be used to more clearly focus all three levels of analysis faster at vastly lower costs with vastly higher levels of validity and reliability.
The results are higher and more precise food safety standards and processes that can be used to guide all three governmental levels and report more focused and accurate results to congress. Now think about the thousands of businesses...farms, distributors, packers, truckers, processors, resturants and grocery stores who have to pay for those long, expensive and unproven, unreliable and invalid audits conducted by an unreliable audit system and questionable auditors. How are they and the food safety system being served and improved? How about OSHA audits? Or hospital audits? Or pharmaceutical audits? Restaurant sanitation audits? Accounting audits? Quality Audits?
