New to this software but appears to be want I needed working with the many aspects of PDF's for our website. PDF Filler offered an excellent annual rate. I am concerned a little about getting to involved with them. You see it happen often after one year with service providers the rates start increasing. Than you need to find a new service to merge your existing business with. We'll see. Overall though the company has been excellent.

Below is a list of the most common customer questions. If you can’t find an answer to your question, please don’t hesitate to reach out to us.
How do you determine validity and reliability of data?
Reliability can be estimated by comparing different versions of the same measurement. Validity is harder to assess, but it can be estimated by comparing the results to other relevant data or theory. Methods of estimating reliability and validity are usually split up into different types.
How do you determine validity and reliability in research?
Overview of Reliability and Validity For research and testing, there are subtle differences. Reliability implies consistency: if you take the ACT five times, you should get roughly the same results every time. A test is valid if it measures what it's supposed to. Tests that are valid are also reliable.
How do you determine validity and reliability?
Reliability is consistency across time (test-retest reliability), across items (internal consistency), and across researchers (interrater reliability). Validity is the extent to which the scores actually represent the variable they are intended to. Validity is a judgment based on various types of evidence.
How do researchers determine validity in a study?
Validity in research refers to how accurately a study answers the study question or the strength of the study conclusions. For outcome measures such as surveys or tests, validity refers to the accuracy of measurement. Assessment instruments must be both reliable and valid for study results to be credible.
How do you know if a study is reliable?
In research terms, reliability refers to consistency. Just as you can count on the consistency of your friend, when something is reliable in science this indicates some level of consistency. In science, validity refers to accuracy. If something is not accurate, it is not valid.
How do you check for the validity and reliability of a questionnaire?
Establish face validity. Conduct a pilot test. Enter the pilot test in a spreadsheet. Use principal component analysis (PCA) Check the internal consistency of questions loading onto the same factors. Revise the questionnaire based on information from your PCA and CA.
How do you check the validity of a questionnaire?
Establish Face Validity. Pilot test. Clean Dataset. Principal Components Analysis. Cranach's Alpha. Revise (if needed) Get a tall glass of your favorite drink, sit back, relax, and let out a guttural laugh celebrating your accomplishment. (OK, not really.)
What is the validity and reliability of a questionnaire?
For a questionnaire to be regarded as acceptable, it must possess two very important qualities which are reliability and validity. The former measures the consistency of the questionnaire while the latter measures the degree to which the results from the questionnaire agrees with the real world.
