Pretty easy to use...so far.
The only thing that concerns me was I didn't realize I had to pay for this until I had finished filling out a complex form. How did i miss that information at the beginning?

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.
How do you achieve validity and reliability in personality tests?
Personality instruments measure samples of behavior. Their evaluation involves primarily the determination of reliability and validity. Reliability often refers to consistency of scores obtained by the same persons when retested. Validity provides a check on how well the test fulfills its function.
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.
Are personality tests valid and reliable?
Personality assessments are valid and reliable. Personality tests are sold on the promise that they are valid (they measure what they say they will measure) and reliable (they produce consistent results). Many studies over the years have proven the validity of the MBTI instrument, says the Myers & Briggs Foundation.
Is the MBTI valid and reliable?
The company's website boasts the assessment has a 90% accuracy rating and a 90% average test-retest correlation, making it one of the most reliable and accurate personality assessments available. Many researchers, however, have long questioned the MBTI's scientific merit.
