🤓 Based on our data, we think this question is relevant for Professor Marsden's class at CAL.

We’re being asked to calculate the average percentage for each set of data given and determine which set is more accurate.

The **average** or **mean **can be calculated using the following equation:

$\overline{){\mathbf{average}}{\mathbf{=}}\frac{\mathbf{sum}\mathbf{}\mathbf{of}\mathbf{}\mathbf{the}\mathbf{}\mathbf{measurements}}{\mathbf{number}\mathbf{}\mathbf{of}\mathbf{}\mathbf{measurements}}}$

**Calculate the average percentage for each set of data:**

Two students determine the percentage of lead in a sample as a laboratory exercise. The true percentage is 22.52%. The students’ results for three determinations are as follows:

1. 22.52, 22.48, 22.54

2. 22.64, 22.58, 22.62

(a) Calculate the average percentage for each set of data, and state which set is the more accurate based on the average.
