One of the ways to improve survey strategies is to validate the survey questions. Validating surveys is not just adding quick survey tips, but it goes beyond. Validity is so much important because it points out what type to survey questions to use. Further, it also helps in ensuring that researchers are using questions to measure the degree of importance.
What is validating a survey?
Validating a survey means assessing the questions depending on the level of usability. There are so many control factors while taking surveys. Validating a survey is not an easy task and can’t be completed quickly.
The methods to validate survey questions are working with OvationMR. They have been conducting research online to help expand opportunities for companies. They work as a team while providing solutions for improving the outcomes.
How to Validate a Survey?
There are six steps to validating a survey, and each of the steps is essential to reach the destination.
- Establishing face validity
It is a two-step process while the survey is reviewed separately by two parties. Likewise, the first party knows the topic well to evaluate the questions. The second party is an expert on question construction. They help in ensuring that the questions don’t contain any errors.
- Running pilot test
Select a subset of the survey and run a pilot test on them. Besides, the sample sizes can vary where 10% of the population consists of solid participants. The more participants you have, you can survey with fewer questions.
- Give clean collected information
While putting the data in spreadsheets, always clean the data. Keep one person reading the values while another enters into a spreadsheet for reducing errors. Double-check the answers for minimum values from the data. For instance, if you have used a five-point scale and see the number 6 in it, there is an error in the data.
- Making use of Principle Components Analysis
PCA allows identifying the components measured with the survey questions. Secondly, this is called factor loading running between -1.0 and 1.0. This step validates what the survey is measuring. PCA is complex and needs an expert to run the action.
- Checking internal consistency
The next step is to review internal consistency for loading the same factors. You can measure the internal consistency with Cronbach’s Alpha. The test values will range from 1 to 10, and the result should be between 0.6 to 0.7 for getting higher consistencies.
- Revising the survey
The final step is revising the survey depending on the questions put forward. If any minor changes are made, it will be ready to view only after the last step. If any significant changes are done, the first pilot test and PCA must be done before moving ahead.
Validating the survey is a crucial factor to indicate that the survey can be dependent on. You can include the validation methods based on the results of the survey. Not just dependability, but validating also adds in a layer of protection and security while giving the final product.
