At first I had an issue with the payment process, but even then the software is wonderful and very easy to use. I am pleased that we were able to resolve the issue and I will continue to use this software on a monthly basis.

Easy to Use but Not Free
This is a typical program that is easy to use as long as you are familiar with PDF editing programs. They do provide tips when you first begin in case you need them. My only complaint and it is for all these "free" programs, is that there are no free programs. All of them make you sign up with your info for a trial period and if you don't like it you better be sure to cancel before the intro period is up or you will be hit with an annual fee.

For pdfFiller’s FAQs
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.
A simple correlation between two scores from the same person is one of the simplest ways to estimate a reliability coefficient. If the scores are taken at different times, then this is one way to estimate test-retest reliability. Different forms of the test given on the same day can estimate parallel forms reliability.
How do you ensure data reliability?
Improve data collection. Improve data organization. Cleanse data regularly. Normalize your data. Integrate data across departments. Segment data for analysis.
How do you ensure validity and reliability in research?
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. The ACT is valid (and reliable) because it measures what a student learned in high school.
How do you ensure validity in research?
When the study permits, deep saturation into the research will also promote validity. If responses become more consistent across larger numbers of samples, the data becomes more reliable. Another technique to establish validity is to actively seek alternative explanations to what appear to be research results.
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 can reliability and validity be improved in research?
Use enough questions to assess competence. Have a consistent environment for participants. Ensure participants are familiar with the assessment user interface. If using human raters, train them well. Measure reliability.
How do you ensure validity in qualitative research?
Credibility. The credibility criteria involves establishing that the results of qualitative research are credible or believable from the perspective of the participant in the research. Transferability. Dependability. Confirm ability.
How can you make research reliability?
This is done by comparing the results of one half of a test with the results from the other half. A test can be split in half in several ways, e.g. first half and second half, or by odd and even numbers. If the two halves of the test provide similar results this would suggest that the test has internal reliability.
