I remember the saying like this one from Stats class way back in the day!
Statistics are biased towards one side
“As long as the errors remain one-sided, it is not easy to attribute them to bungling or accident.”
Nobody uses statistics to disprove themselves. That is, statistics are used to serve a cause or agenda that someone believe ins, rather than disprove that cause or agenda. So when people err in their use of statistics or make intentional mistakes, the errors will always be in one direction (the direction of their beliefs and agenda). So instead of getting an unbiased look at the world, we’re getting a biased look of the world that other people want us to see. This is a dangerous world to live in if you don’t recognize this reality about how people use data.
I remember the professor I had told us to use the numbers in off the wall cases and present to class as small groups. It was an interesting exercise and actually comical. To bad this was way before smartphones and youtube etc. Would of been great to get some recording of the Bull Sh*t we were saying twisting the numbers.
