Which of the following is FALSE? If a measure is reliable, it is not heavily influenced by transitory factors that cause random errors. If an item lacks correlation with other scale items measuring the same construct, there is evidence that the item does not belong and should be deleted. Systematic error is due to temporary aspects of the person or measurement situation, which affects the measurement in irregular ways. Reliability is necessary, but not sufficient, for establishing the validity of a measure. If a set of items all measure the same construct, the responses to the items should be correlated.
