Correction: Lin et al. A Perception Study for Unit Charts in the Context of Large-Magnitude Data Representation. Symmetry 2023, 15, 219

Text Correction

There were two errors in the original publication [1].

1. 

Post hoc multiple comparisons are not described in the format of APA.

The following correction has been made to Section 3. Experiment 1: Measurement for the Discrimination Threshold of Unit Charts, Section 3.5. Results, Paragraph 1:

“The overview of collected JND data is shown in Figure 4a. The data were analyzed using SPSS statistical computer software (SPSS, Inc., Chicago, IL, USA). Statistical analysis included one-way ANOVA followed by Tukey-b or Tamhane tests, as required for each variable [54]. The box plot is shown in Figure 4b, and no outliers were identified. Post hoc multiple comparisons were determined using the Tamhane procedure, and the results showed that the mean JND of unit charts when representing tens digits (M = 7.35 px) is significantly lower than that when characterizing hundreds digits (M = 8.38 px) and thousands digits (M = 9.29 px). The results of multiple comparisons are shown in Table 1. Unit charts that represent larger magnitudes had larger mean JNDs.”

2.
