Question

the following graph shows the vitamin a content (in ius, international units) for 23 types of fruit.
which of the following would be the best measure to describe the center of this distribution?
(a) mean
(b) median
(c) standard deviation
(d) interquartile range
(e) range

Explanation:

Step1: Analyze the data distribution

The data has an outlier (the value near 4000). The mean is affected by outliers. The range is a measure of spread, not central tendency. The standard deviation is also affected by outliers.

Step2: Recall the property of median

The median is the middle - value when the data is ordered. It is not affected by extreme values (outliers).

Answer:

B. Median
