IA - 4 - Using Desmos to Graph Uncertainties

What is the primary purpose of using Desmos in this context?

• To store raw experimental data.

• To perform complex statistical analysis.

• To visualize experimental data and its uncertainties.

• To simulate physical phenomena.

In the experiment, which variable is considered the independent variable?

• Time (t)

• Average Time

• Distance (d)

• Uncertainty in Time

How are vertical error bars added to the graph in Desmos?

• By plotting x = x1 {y1 - z1 < y < y1 + z1}

• By plotting x = x1 {y1 - z1 < y < y1 + z1}

• By plotting y = y1 {x1 - 0.5 < x < x1 + 0.5}

• By plotting x = x1 {y1 - 0.5 < y < y1 + 0.5}

What is the uncertainty value used for the horizontal error bars in the distance measurement?

• ±0.03 cm

• ±0.05 cm

• ±0.5 cm

• ±0.04 cm
