Subclaims¶

q2 i? In a pilot study with 30 subjects, the 13-question Statistical Reasoning Assessment obtained a Cronbach alpha of .82, which the authors take to indicate reliability. → Nanteni Ganesan & Leong Kwan Eu 2018

q2 · i? · causal · r2

Pilot study conducted at secondary schools in Klang under conditions similar to the actual study, using internal-consistency reliability because the test was administered only once. The instrument has thirteen questions gauging statistical reasoning.

"There were 30 subjects in the sample ( N=30) participated and the Statistical Reasoning Assessment instrument obtained Cronbach Alpha of .82 hence the coefficient indicated that the instrument were reliable."
