(1) Give a challenge that maybe encountered in understanding and/or analyzing statistical concepts and methods.

One challenge in understanding statistics is to understand how assessment outcomes are affected by reliability. Reliability is one of the most important characteristics of a good assessment because it shows the consistency of a specific measurement. For example, the reliability of a test measures its ability to measure a trait consistently (each time). However, as Mitchell and Jolley (2005) note, one reason that a reliable measure may not be valid is that it is reliably consistent in measuring the wrong thing" (P.107). For instance, research shows that with the advancement of new technology (e.g. computational assessments) in assessments, a major challenge exists regarding the understanding of statistical concepts and procedures. For instance, they assert that students' use of new technologies raises questions as to the need to address challenges in how students' conduct assessment, and ...
