EXPERIMENT 1. STATISTICS about 3 m high” or ”the bus is around 3 m high”, but in a scientific context, such general phrases are not useful - instead we express our uncertainty quantitatively (with numbers). When pressed the bus driver might admit that his estimate that the bus is 3 m high is only a guess, but he is confident it is less than 3.3 m high and that it is greater than 2.7 m high, so he could say that the bus is between 2.7 m and 3.3 m high. Even better would be a statement that he believes the bus is 3.0 m high with an uncertainty of ± 0.3 m (i.e. between 3.0-0.3 m and 3.0+0.3 m). This is the proper way to report the result of a measurement in scientific context. In the previous example the bus driver didn’t actually measure the height of the bus. If he had parked the bus in front of a tile building with tiles that he knew to be 0.3 m square he might have been able to count the rows of tiles from the ground to the top of the bus to determine the height of the bus. If he sees the bus is between 9 and 10 tiles high he can state the height of the bus is 9.5

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
