Answer:
the measure of center that best describes the data is the median
Explanation:
Measures of central tendency can be measured using the mean and median
Arranging the data: 8, 11, 12, 14, 15, 18, 42
The mean = (sum of values)/(number of values in the data set)
number of values in the data set = 7
The mean = (8+ 11+ 12+ 14+ 15 +18 + 42)/7
The mean = 120/7
The mean = 17.14
The median of the data = 14
To determine the measures that best describes the data, we would compare the data and result obtained as mean and median.
Most times the mean is used to describe the data but if their is an outlier, the median is preferred.
We can tell from the data that their is an outlier (42). It is far from other numbers in the data set.
Also, the median best describes the scores because the mean is higher than most of the scores in the data set.
Therefore, the measure of center that best describes the data is the median
