Question

The median of the given data is
89, 45, 56, 67, 89, 45, 78, 45, 78, 45, 67

• A. 67.5
• B. 134.5
• C. 67
• D. 56

Hint:

To find the median, first arrange the data in ascending order and then select the middle value. If there are an even number of values, take the average of the two middle values.

Answer 1

The Correct Option is C

Step 1: Organize the data.
The given data set is: 89, 45, 56, 67, 89, 45, 78, 45, 78, 45, 67. Arrange the data in ascending order: \[ \text{45, 45, 45, 56, 67, 67, 78, 78, 89, 89}. \]

Step 2: Find the median.
The median is the middle number of a data set. For an odd number of values, it is the middle one. For an even number of values, it is the average of the two middle values. Here, we have 11 values, so the middle value is the 6th value. The 6th value is 67.

Step 3: Conclusion.
Therefore, the median is 67.

Final Answer: 67.
