place: To carry out simple experiments to determine whether or not an ordinary six-faced gaming extend is bias or not.
VARIABLES: Independent- surface of the separate
Manipulated- contrasting types of experiments
Responding- faces of the die
Procedure:
1. Students were place into six multitudes of threes and fours. Each group randomly choose one of the experiments below, (i to vi) to carry out in which from each one group had to throw an ordinary 6-faced gaming die one hundred and twenty quantify on different surfaces.
(i) The die was held in the palm of the hand and shaken or so a a some(prenominal) times before it was thrown onto a varnished display panel top.
(ii) The die was placed in a Styrofoam drinking cup and shaken around a hardly a(prenominal) times before it was thrown onto a varnished instrument panel top.
(iii) The die was placed in a rubbish drinking cup and shaken around a few times before it was thrown onto a varnished skirt top.
(iv) The die was held in the palm of the hand and shaken around a few times before it was thrown onto a cloth cover table top.
(v) The die was placed in a Styrofoam drinking cup and shaken around a few times before it was thrown onto a cloth covered table top.
(vi) The die was placed in a glass drinking cup and shaken around a few times before it was thrown onto a cloth table top.
2. When all groups carried out their experiments, all of the results were then combined.
3. A table was constructed with the frequencies of each face landing uppermost face on the die.
4. Using Microsoft excel, charts were then made for each of the experiments to show comparisons of the frequencies for each face
5. For each experiment, the relative probability was calculated for each face landing uppermost. All results were tabulated.
6. All findings and comparisons were discussed and a conclusion was stated.If you regard to get a full essay, order it on our website: Ordercustompaper.com
