# Skill: Uncertainty

## How Speedy are These Muons?

In this activity, students use authentic detector data to apply simple 1D kinematics (v=d/t), interpret graphical data, and evaluate measurement uncertainties.

## Angles and Dimuons

This activity is based on the data analysis used for World Wide Data Day,

## CMS Masterclass WZH-path

Students are physicists for a day at a university or lab where they work with physicists to learn how to analyze real particle physics data in the form of event displays.

## Histograms: Uncertainty

Students construct histograms, identify the best value to represent the data, and report the uncertainty in their answers.

## Histograms: The Basics

Students build basic histogram skills required in many of the other activities in the Data Activities Portfolio.

## Mean Lifetime Part 3: MINERvA

Students collect data from muons which decay in the MINERvA detector in the Fermilab NuMi beamline to understand particle decay and determine the muon lifetime.

## The Case of the Hidden Neutrino

Students use momentum conservation to examine the decay of top-antitop pairs to determine what is missing from the event.

## Signal and Noise: Cosmic Muons

In this introductory tutorial that, students learn about how to distinguish muon signals from background and instrumental noise.

## Signal and Noise: The Basics

Students analyze signals and noise first in audio and video forms and then look at signals and noise from physics measurements.

## CMS Masterclass J/Psi

Students are physicists for a day at a university or lab where they work with physicists to learn how to analyze real particle physics data in the form of event displays.
