Question
Where can I find graphs statistics and other information on the results of standardized tests?
Answer
There is a general perception that statistical knowledge is all-too-frequently intentionally misused, by finding ways to interpret the data that are favorable to the presenter. (A famous quote, variously attributed, but thought to be from Benjamin Disraeli is: "There are three types of lies - lies, damn lies, and statistics." The well-known book How to Lie with Statistics by Darrell Huff discusses many cases of deceptive uses of statistics, focusing on misleading graphs. By choosing (or rejecting, or modifying) a certain sample, results can be manipulated; throwing out outliers is one means of doing so. This may be the result of outright fraud or of subtle and unintentional bias on the part of the researcher.
