Investigation of the Relationship between Visual Measurements and Test and Item Statistics

The purpose of this study was to investigate the correlations between time-and count-oriented visual data collected from a wearable eye tracker and test and item statistics. To accomplish this, a wearable eye tracker was used with an achievement test that included 30 multiple-choice questions assessing eighth-grade achievements, administered to 60 high school students. The acquired data were then used to compute t-values, Pearson correlation coefficients, and regression coefficients. The results of the study demonstrated a substantial inverse relationship between time and count-oriented visual assessments and achievement scores. Furthermore, time and count-oriented measures were shown to be significant predictors of achievement test results. Additionally, substantial disparities in times to first fixation and total durations of visit were identified in favor of females, whereas significant differences in average durations of visit were discovered in favor of males. The results of this study show that there is a substantial association between time-oriented measures and test and item statistics.
