Control Demonstration
We did a mock experiment in class today. The experiment was on how reaction rates vary according to sex, and Mr. Anthony's hypothesis was that males would be faster than females. He demonstrated how biases could introduce confounding variables into an experiment and manipulate the results. Mr. Anthony allowed a male student to pick the hand he caught a measuring stick with, to sit down, and to predict the drop time, in contrast with the disadvantages the female student was subjected to. With a second pair, the male student was able to predict the time of fall, got praise, and was asked whether he was ready.

Sunny, confounding variables can also be introduced by mistake as well as by biases.
Could be argued that mistakes are often the product of biases :D
I hope you're doing well Mr. A
