Subclaims¶

q2 i? Chatbot engagement was long-tailed and zero-inflated: mean use was 29.20 interactions (SD = 52.14) and about 27% of students never used StatBot. → Yuan-Hsuan Lee and Jiun-Yu Wu 2026 q2 i? Weekly usage tracked assignment deadlines, peaking mid-semester in three distinct phases. → Yuan-Hsuan Lee and Jiun-Yu Wu 2026 (2)

q2 · i? · associational · r1

Descriptive analysis of 2,819 logged StatBot interactions from 97 graduate students over 16 weeks showed a long-tailed, over-dispersed, zero-inflated usage pattern, with individual interaction counts ranging from 0 to 401 and roughly 27% of students never using the tool.

"On average, students engaged with the StatBot 29.20 times ( SD = 52.14), indicating substantial variability and a highly skewed distribution ( skewness = 4.31; kurtosis = 25.15). About 27% of students did not use StatBot at all and a few used it over 100 times."

q2 · i? · associational · r2

Weekly usage counts across the 16-week semester (range 10–365, mean 192.81, SD = 137.14) showed three phases: steady early adoption, a sharp mid-semester peak around assignment deadlines, and a drop to a lower stable level during final project and exam preparation.

"The overall trend shows a strong association between StatBot usage and assignment deadlines, peaking dramatically mid-semester before stabilizing at a lower level for final project and exam preparation."
