Question

Quizplus · Accepted Answer

To determine an instrument's homogeneity, a nurse researcher typically uses split-half reliability. This type of reliability involves splitting the instrument into two halves and then comparing the results of each half to ensure that they are consistent. The nurse researcher can use a variety of statistical methods to evaluate the instrument's homogeneity, such as the Spearman-Brown formula, the Kuder-Richardson formula, or Cronbach's alpha. Split-half reliability is often used for instruments that measure constructs with multiple items, such as questionnaires or surveys.
