**Statistical Analysis of Laboratory Result: Accuracy and Precision** Shantel was exploring the different types of glassware in the chemistry lab and wanted to compare how well a graduated cylinder delivered 5.00 mL of water. The below data was collected by weighing an empty beaker, zeroing the balance, and weighing the water delivered. The temperature of the water is 20.4°C. The density of water at this temperature is 0.998120 g/mL. **Objective:** Determine the average, % error, standard deviation, and coefficient of variation (CV) for the graduated cylinder. You may do the calculations in Excel if you wish. Report your answers to the appropriate number of significant figures. **Data from Trials:** - Trial 1: 4.9821 g - Trial 2: 4.9745 g - Trial 3: 5.0112 g - Trial 4: 5.0041 g

Shantel was exploring the different types of glassware in the chemistry lab and wanted to compare how well a graduated cylinder delivered 5.00 mL of water. The below data was collected by weighing an empty beaker, zeroing the balance, and weighing the water delivered. The temperature of the water is 20.4°C. The density of water at this temperature is 0.998120 g/mL.
**Objective:**
Determine the average, % error, standard deviation, and coefficient of variation (CV) for the graduated cylinder. You may do the calculations in Excel if you wish. Report your answers to the appropriate number of significant figures.
**Data from Trials:**
- Trial 1: 4.9821 g
- Trial 2: 4.9745 g
- Trial 3: 5.0112 g
