An important measure for controlling bias (APEX)
Different types of clothing and a backpack. A backpack must be controlled in this experiment. Hope this helps students. ( Science Teacher ) :)
an experiment is: How many students at your school like Doritos and Cheetos? Which is preferred ?
Randomizing the unwanted variables is one method of building a stronger causal argument. Controlling or a strong attempt at controlling the unwanted variables would be recommended. One variable, and only one should remain independent; this would ensure the dependent variable could be assessed in the proper light. Eliminating unwanted confounding variables my be necessary for a stronger causal argument; the confounding variables distort the conclusion in the causal argument. Eliminating unwanted variables could mean categorising data; it could mean separating data; it could mean some guess work, such as adding/subtracting figures like a statistician.
His score on the retest was higher than on his first attempt. Colleges regularly retest their incoming students in math before assigning them to classes.
The students acting as prisoners were showing signs of extreme distress.

randomly
100% - 40% = 60% are not.
Depends on the school, but most beauty schools encourage students to experiment and have different looks.
85/500 = 17%
