Lab Partner: Amy Hayes Question 4: Both the height and diameter of the cylinder were taken to find the volume; five times for both measurements. Vernier calipers were used to get these measurements by clamping the cylinder between the jaws of the calipers. By looking at the mark of the zero‚ in relation to the main scale‚ the line best lined up with a line from the main scale was taken down. Getting these numbers we can further calculate values for average

Methodology Figure 1: Experimental set-up using vernier caliper Figure 2: Micrometer caliper In the experiment‚ three measuring devices are used to obtain the measurement of a sphere with known composition: vernier caliper‚ micrometer caliper and a foot rule. Ten individual measurements are then made for each of the device. After the measurements are obtained‚ the mean diameter of the sphere was

Error Analysis Lab By: Lab Team 5 Introduction and Background: In the process of learning about the importance of measurement and data processing‚ lab teams were given prompts to design experiments as well as address the precision‚ accuracy‚ and error analysis within the experiment. Lab teams collaborated their data to find similarities and differences within their measurements. Through this process‚ students learned the importance of the amount of uncertainty as well as the different
