In the movie, Mean Girls, there was definitely a gender bias. The main character is a girl named Cady. Cady is amazing at math, and she has a great understanding of the subject. Cady is a junior in high school, and has never before gone to a real school. At first, she tries hard and does well. But by the middle of the year, she has developed a crush on the boy who sits in front of her, named Aaron. Because she is too scared to talk to him on her own, she dumbs herself down and asks for his help. This shows that sometimes there is a gender bias in the classroom because girls are uncomfortable with seeming smart, so they purposefully pretend to be stupid. That makes it seem like boys are smarter, because they get better grades, when really girls have the same ability level. Another example of gender bias is when Cady is forced is forced to join a math club, and all of them are boys. Not only is she forced to join because of how good she is, but also because the club will get more funds if there is a female on the team. If there wasn't a gender bias, then the club wouldn't have gotten more money just because there's a girl on the team.
