Travis Marziani Physics 221 Experimental Uncertainty (Error) and Data Analysis Abstract In this experiment data analysis and experimental uncertainty is examined. This comes in handy to know that just because someone measures something doesn’t mean that it’s exactly accurate, and that there is some room for error. In this experiment different numbers were taken and placed in both or either scientific notation or change it into significant figures. From doing this we see that the measurements and numbers that come from our data are not exactly accurate and must be taken as close but only exact to two or three place values.

Unformatted text preview: Conclusions In conclusion this experiment shows how experimental uncertainty and error analysis becomes very important especially when trying to figure out something as precise as possible. Data of gravity was used to show how off numbers can be when analyzed. The value obtained using the graph were the points (.85, 4.2) and (.35, 2) were used to access the slope and thus the acceleration of gravity, the value obtained was 8.8 m/s^2. Which is noticeably off by 10.2%. In the rest of the lab numbers were changed to both scientific notation and were accessed for significant figures....
