Split-Half and Odd-Even

  • Split half refers to determining a correlation between the first half of the measurement and the second half
  • Odd-Even refers to the correlation between the even items and odd items of a measuring device.
  • In this sense, we are using a single test to create two tests, eliminating the need for additional items, the need for multiple administrations, and the memory effect
  • Since in both of these types of reliability only one administration is needed and the groups are determined by the internal components of the test, these methods are called internal consistency measures of reliability
