There was a mistake in Table 1 as published. In the “Variable” column, subheading “Gender,” the published word “Girls” corresponding to frequency number 427 (in the second column) should be corrected as “Boys,” and the word “Boys” corresponding to frequency number 356 (in the second column) should be corrected as “Girls.” The corrected Table 1 appears below.

A correction has been made to the Results section, paragraph one. In the published article, there was a mistake in the statement of the percentage of students by gender in the Results section. The percentage was displayed as “Amongst 783 students, 54.5% were girls, 61.0% were in junior grade level.” The correct statement is “Amongst 783 students, 54.5% were boys, 61.0% were in junior grade level.”.
