Detailed explanation-1: -The calculation of indicator reliability can be performed by squaring the values in the indicator/factor loading. The squared value >= 0.50 indicates the indicator reliability is established. In case you obtain weaker indicator loadings (< 0.708) .

Detailed explanation-2: -This measure of reliability is described most often using Cronbach’s alpha (sometimes called coefficient alpha). It measures how consistently participants respond to one set of items. You can think of it as a sort of average of the correlations between items.

Detailed explanation-3: -Cronbach’s alpha yields a value that represents the average of a number of correlation coefficients. A commonly used indicator of inter-rater reliability is called Cohen’s Kappa.

Detailed explanation-4: -Reliability is another term for consistency. If one person takes the samepersonality test several times and always receives the same results, the test isreliable. A test is valid if it measures what it is supposed to measure.
