Numbers don't lie...do they?

If you are speaking about statitistics the answer may not always be what it seems. Depending on who is providing the statistic and where the statistic orginated from could give you drastically different results.  If one were to say that 40 % of students are struggling with ADD or ADHD, where did they recieve their data? Was it just a number that they through out or is there an actual case study to back up the data?  If it is a study, who was included in the study? Is it elementary, middle school, high school, or college students? Then ask yourself, is it really possible that all students have been tested for ADD or ADHD?  Anyone can give you numbers, it is where the information orginated from and what was included. Do not just take a number for face value, it could be an illusion.
