How do I record and calculate my burette readings and average volume for a titration experiment, given methyl orange as the indicator?

Since I cannot perform the experiment, I will provide the template for your results and explain how to calculate the average volume.

Tabulate your burette readings.
You should record your initial and final burette readings, and then calculate the volume of solution A used for each titration. Aim for at least two concordant readings (within $\pm 0.10 \text{ cm}^3$ of each other).
$\begin{array}{|c|c|c|c|} \hline \textbf{Titration Number} & \textbf{Final Burette Reading} \ (\text{cm}^3) & \textbf{Initial Burette Reading} \ (\text{cm}^3) & \textbf{Volume of A used} \ (\text{cm}^3) \\ \hline \text{Rough} & & & \\ \hline 1 & & & \\ \hline 2 & & & \\ \hline 3 & & & \\ \hline \textbf{Average Volume of A used} & & & \\ \hline \end{array}$
Calculate the average volume of A used.
Select the concordant titre values (those that are very close to each other, typically within $0.10 \text{ cm}^3$ ). Sum these concordant values and divide by the number of values.

For example, if your concordant readings were $24.00 \text{ cm}^3$ , $24.10 \text{ cm}^3$ , and $24.05 \text{ cm}^3$ :
$\text{Average volume of A used} = \frac{24.00 \text{ cm}^3 + 24.10 \text{ cm}^3 + 24.05 \text{ cm}^3}{3} = \frac{72.15 \text{ cm}^3}{3} = \boxed{24.05 \text{ cm}^3}$
Indicator information.
The indicator specified is methyl orange. In an acidic solution, methyl orange is red/pink. In a basic solution, it is yellow. At the endpoint of this titration (weak acid with strong base), the color change will be from yellow to orange.
