Using Statistical Data and Graphs (Part II)

Jan. 8, 2012 - 5th Meeting of Physics 101.1 Lab

This is the continuation of my post about using statistical data and graphs. In this part of the lecture, we studied the use of Scatter or X and Y Graph. A scatter plot or scattergraph is a type of mathematical diagram using Cartesian coordinates to display values for two variables for a set of data. Unlike linear graphs, the scatter plots only the points and connects them in an uneven manner.

Here's the scatter plot that we have done during the experiment. The experiment describes the movement (position, velocity, and acceleration) of a ball which is thrown upward on a remote sensor. Graphical results are propagated from the vernier lab quest.

Then, we also had an experiment that examines the motion of a linear particle (like a ruler) through a photogate, an instrument that somehow measures the motion of a particle. These are our results: 

The results shown here are represented by a line with bars on their edges, that indicates uncertainty.

The experiment was a first: a preparation for the next activities. Although it was a little tedious, the experiment was done enthusiastically. --Bartz, 2012
