Throughout our study we discovered several weaknesses that may have influened our data. First, several people
responded to the survey with more than one letter grade circled. We still used those because with those we had exactly 75 returned to us. We just rounded down a letter grade  We also recieved blank surveys back because they werent in that class anymore, are now homeschooled, or were not sent to the right room.Some people didn't respond at all. A large bias, of course, would be that people didn't respond with their actual average grade. They either could not remember exactly or were embaressed to say they failed the class or got a low grade. We recieved no F responses and there were many high grades circled.  

Extrapolate

We figured we could extrapolate our data and study to nearby schools surrounding North Olmsted to see what, if any, varying results would be different for different schools. We decided we would be comfortable extrapolating to any public school because we all take algebra and geometry and there would be no varying factors, besides perhaps different teachers with different teaching styles.

Suggestions

To further work in our topic, we could have asked more detailed questions and opinions to people who took such classes as, 'did you find one class harder than the other?' Also, if we wanted more accurate results we could have asked teachers to share solid, concrete information on grades depending on classes-not child specific of course- to obtain more accurate data.
