Question 20

The median of the sales-receipt data is $34.

The median is the middle value in a sorted list of numbers. In this case, after organizing the sales-receipt data, the value that falls in the center is $34.

A) $25

Option A is incorrect because $25 does not represent the middle value of the sorted dataset. It is lower than the actual median, indicating that it does not reflect the central tendency of the sales-receipt data.

B) $34

Option B is correct as it accurately represents the median value of the sorted sales-receipt data. This value is positioned centrally, confirming its role as the median.

C) $41

Option C is incorrect because $41 is higher than the median value. While it may be a part of the data set, it does not serve as the middle value when the data is arranged in order.

D) $48

Option D is also incorrect as $48 is the highest value in the dataset and does not fall near the middle. Thus, it cannot be considered the median.

Conclusion

The correct answer, $34, is definitively the median as it is the middle value of the sorted data. All other options fail to represent the central tendency accurately, either being lower or higher than the median. This emphasizes the importance of identifying the correct median in a dataset for accurate analysis.
