This study explores common biases in educational settings, specifically focusing on gender performance. It highlights the notable difference in performance outcomes between girls and boys, evidenced by the number of stars awarded for performance. The findings suggest that girls outperform boys significantly, particularly in reading skills. The analysis also includes statistical jargon, such as standard deviation and chi-squared index, to provide insights into the validity of the marking scheme. The implications of these findings could inform teaching practices and assessment strategies.
