Filtering of Data from excel masterclass
Here are three graphs that show what we have been doing at QuarkNet to filter the data to see different peaks in the data. As it says on the graph, this is the calculated mass of the data we have taken so far in Masterclass. We realized that there was a large peak around 80-90- Giga Electron Volts which makes sense because we are looking at the Z and W particles in this Data.

Now that I have looked at the calculated mass of all the particles, I now filtered out the Z candidates in the data to look at where the all came out to be in the graph Z vs. Mass. As you can see, just like the calculated mass, the peak is around 90 GeV which is where the particle usually is found.



This graph shows the W candidates and their peaks, but this is different from the Z candidates because most of the peaks in the data are from sixty to eighty, while the Z candidate was around 90 GeV. By looking at the total calculated mass at the top, and then adding the W and Z together, you can see how the two layers fit into each other to make the final calculated mass of all the particles.
