Abstract

This study aims to analyze the effectiveness of various types of graphic visualizations in improving audience understanding of statistical presentations in Indonesian. Using a descriptive quantitative approach, data were collected through an online questionnaire from 30 college students. Five types of graphs (bar, pie, line, scatter plot, and horizontal bar) were tested for their ease of understanding and interpretation accuracy. The results showed an average interpretation accuracy of 80.7%, indicating the high effectiveness of Indonesian-language graphs. The bar chart was rated the easiest to understand (mean 4.10) with 86.7% accuracy, while the horizontal bar chart recorded the highest accuracy (90.0%). Conversely, the scatter plot was perceived as the most difficult (mean 3.37), although its objective accuracy remained good (80.0%). The clear use of the Indonesian language and graphic design quality proved to be highly positive in aiding audience understanding. In conclusion, Indonesian-language graphic visualization effectively communicates statistical data, with bar charts being the most accessible medium.
