Data Interpretation:
The following table shows the number of students in five different colleges. Answer the questions based on the data.
\[
\begin{array}{|c|c|}
\hline
\text{College} & \text{Number of Students} \\
\hline
\text{A} & 1000 \\
\text{B} & 1500 \\
\text{C} & 1200 \\
\text{D} & 1300 \\
\text{E} & 900 \\
\hline
\end{array}
\]
Question: What is the average number of students in all five colleges?
Show Hint
In data interpretation problems, always find the total sum first, and then divide by the number of entities to find the average.
The mean student count is determined by dividing the total student count across all institutions by the number of institutions:\[\text{Average} = \frac{1000 + 1500 + 1200 + 1300 + 900}{5}\]\[\text{Average} = \frac{5900}{5} = 1200\]Answer: The average student count is 1200. This corresponds to option (1).
