I own a few franchise restaurants and have to use this product about once a week and it makes my time with documents way faster and easier. I don't have to download a document, scan it, sign it, and then rescan it and then send it. I can do it all electronically thanks the PDFfiller.

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.
MTBF is a basic measure of an asset's reliability. It is calculated by dividing the total operating time of the asset by the number of failures over a given period of time. Taking the example of the AHU above, the calculation to determine MTBF is: 3,600 hours divided by 12 failures. The result is 300 operating hours.
How can reliability of a test be solved?
To calculate: Administer the two tests to the same participants within a short period of time. Correlate the test scores of the two tests. Inter-Rater Reliability: Determines how consistent are two separate raters of the instrument.
How do you test for reliability?
Examples of appropriate tests include questionnaires and psychometric tests. It measures the stability of a test over time. A typical assessment would involve giving participants the same test on two separate occasions. If the same or similar results are obtained then external reliability is established.
How do you determine reliability of a test?
Test-retest reliability is a measure of reliability obtained by administering the same test twice over a period of time to a group of individuals. The scores from Time 1 and Time 2 can then be correlated in order to evaluate the test for stability over time.
What does reliability of a test mean?
Test Reliability and Validity Defined Reliability. Test reliability refers to the degree to which a test is consistent and stable in measuring what it is intended to measure. Most simply put, a test is reliable if it is consistent within itself and across time.
How do you determine reliability in research?
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 know if an experiment is reliable?
A measurement is reliable if you repeat it and get the same or a similar answer over and over again, and an experiment is reliable if it gives the same result when you repeat the entire experiment.
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.
