# Analyzing and Interpreting Data

## Introduction

Analyzing data means to use information you have from graphs, charts, tables or any other representations of data to form inferences and interpretations. Scientists analyze data so that they can learn more about their surroundings and figure out meaningful information from their labs, experiments, and tests. Quantitative data is data that represents numbers and statistics. Qualitative data is data that represents the qualities of an object. Examples of this include the objects' color, texture, and shape. Some tools I used in Physics this year include VideoPhysics, stopwatches, rulers, and the launching metal plunger.

## Artifact One

### Force, Mass, and Acceleration Lab

In the Force, Mass, and Acceleration Lab we used a metal launching plunger as our tool. It worked really well and gave my group a lot of very valuable information. We put weights on the moving vehicle that traveled on the plunger. When we pressed the button, the vehicle was launched from one side to the other. The plunger was connected to a computer which tracked the speed, acceleration, and velocity of the moving vehicle and produced graphs with that information for us. From the information provided from the plunger and computer software combination, I was able to figure out the Net Force of the moving vehicle while it carried different weights.

## Artifact Two

### Vertical Projectile Lab

In the Vertical Projectile Lab, my group used multiple tools to help us including a tennis ball , a meter stick, and the VideoPhysics iPad App. In the lab, we videotaped someone throwing the ball up in the air against the meter stick. It was released and then caught at the same height. We then put the video in VideoPhysics. After tracking the motion all the way up and back to your hand, we were able to create graphs that provide us with information on the tennis ball's acceleration and velocity. We then were able to analyze the information and form conclusions regarding it. I learned that both the velocity and the acceleration remained the same/stayed constant over time.
