How to Do It Collingridge outlines a six-step validation method he has successfully used over the years.
Step 1: Establish Face Validity This two-step process involves having your survey reviewed by two different parties.
What It Means Validating a survey refers to the process of assessing the survey questions for their dependability.
Because there are multiple, tough-to-control factors that can influence the dependability of a question, validating a survey is neither a quick nor easy task.
The first is a group familiar with your topic who can evaluate if your questions successfully capture your topic.
Therefore, it is important data validation occurs before doing any analyses or creating tables or reports from the data you plan to use, whether it is new data or data from an outside source.
A process associated with the collection and production of intelligence that confirms that an intelligence collection or production requirement is sufficiently important to justify the dedication of intelligence resources, does not duplicate an existing requirement, and has not been previously satisfied.2.
In computer modeling and simulation, the process of determining the degree to which a model or simulation is an accurate representation of the real world from the perspective of the intended uses of the model or simulation.3.Single select questions are appropriate when: A few examples of single select questions are yes-no, select best that applies, or preference scales.Data mining is the process of sorting through large data sets to identify patterns and establish relationships to solve problems through data analysis.Triangulation means using more than one method to collect data on the same topic.This is a way of assuring the validity of research through the use of a variety of methods to collect data on the same topic, which involves different types of samples as well as methods of data collection.To reduce the mental roadblocks in understanding statistics, there aren't any equations in this lesson.
