In clinical study or epidemic research, the 2×2 frequency table is useful to present a summary statistic. The values of four cells in 2×2 table use to calculate the effect measures such as risk ratio, relative risk ratio or odds ratio. In this paper, we suggest that the improved visualization method using a radar diagram supported by MS-office Excel from the 2×2 frequency table is able to understand and draw easily betweendiagnostic measures such as sensitivity, specificity, predictivity, and
