Rarely, proton pump inhibitors (such as omeprazole) have caused vitamin B-12 deficiency. The risk is increased if they are taken every day for a long time (3 years or longer). Tell your doctor right away if you develop symptoms of vitamin B-12 deficiency (such as unusual weakness, sore tongue, or numbness/tingling of the hands/feet).
Stability reliability refers to the consistency of students' scores when a test is administered to the same students on two different occasions. Alternate-form reliability describes the consistency of students' performances on two different (hopefully equivalent) versions of the same test.
In research, the term reliability means repeatability or consistency. A measure is considered reliable if it would give us the same result over and over again (assuming that what we are measuring isn't changing!).Let's explore in more detail what it means to say that a measure is repeatable or consistent.We'll begin by defining a measure that we'll arbitrarily label X.It might be a person's score on a math achievement test or a measure of severity of illness.et's explore in more detail what it means to say that a measure is repeatable or consistent.
