Should Participants Of A Field Experiment Be Debriefed?
Answer:
It depends on the design of the experiment, the data you collected, what you plan to do with the data, how much hysterical investment the participants have in the experiment or the outcome, and other factor. It is probably a good idea to debrief the participants, unless the number of them or their anonymity prevent it.
Some may hold comments, expectations, ideas for experiment design, theories regarding the hypothesis you are measuring, or other input that will suggest different experiments or indicate reasons why the present one is invalid. You want to know these things. Others may suffer emotional trauma related to their expectations of their own performance, that of others, or the experimental outcome. You want to know this and buy and sell with it, too.

What Is The Distance Between The Pair Of Points:(1,3), (-2,4),(0,-4)...
To find distance between two pair of points we would use the formula: Distance between two points= √((X2-X1) 2 +(Y2-Y1) 2 ) Now let us suppose: A=(1,3) B=(-2,4) C=(0,-4) Now lets plug within the values of x,y in the equation to obtain the distance...
