Purpose: To find out if people really do know the difference between tap water and.
bottled water or is it just in there head. .
Subjects: Our class, fifth period statistics. The class is arranged alphabetically and then .
spilt into two; the first thirteen will be group 1 and the last thirteen will be group 2. .
Experiment: In this experiment 26 cup were filled with tap water and 26 were filled.
with Bottled water (Poland Springs). Treatment A will be the Tap water and treatment B will be the bottled water, which is Poland Spring. Group 1 will be given treatment A and asked what they think that it is then they will receive treatment B and again asked what they think that it is. Group 2 will do the opposite they will get treatment B then treatment A. (See diagram below).
Data:.
Group 1.
Guessed Bottled Guessed Tap.
.
Poland Springs 6 7.
.
Tap Water 4 9.
Group 2.
Guessed Bottled Guessed Tap.
.
Poland Springs 8 5.
.
Tap Water 5 8.
Conclusion: In looking at the data it is obvious that 14 people guessed correctly for.
Bottled water and 17 knew that the tap water was really tap. This experiment shows that more people can taste when they are drinking tap water and they have a harder time deciding what the bottled water was. Group one's data is interesting, meaning that some of the people thought that both treatment A and B were the same, which in fact they were not. This here can help prove the point that many people can not tell the difference between tap water and Bottled water. One lurking variable that must be taken into consideration is the place in which the tap water was taken from. Different neighborhoods even have different water.
Summary: Basically all that this experiment was trying to prove was weather or not.
people could really tell the difference between regular water form the spigot and water that has been bottled. And as stated above, some cannot tell the difference and others really can.
