One study mentions that they found over 90% of the nation's school districts reported that their students were scoring "above the national average." Explain why this report is incorrect.
Does the analysis change if the term "average" refers to mean? What about the median?
I think this is incorrect since it should be exactly 50% above average and 50% below average. I'm not sure if it changes when it's referring to the mean, because the mean can get skewed by outliers, right? I know that it's incorrect when referring to the median because median is the center again.
