The data set gives the number of hours it took each of the 10 students in a cooking class to master a particular technique. Which of the numbers below is the best measure of the central tendency of the data?

Question

{3, 3, 4, 4, 4, 5, 5, 5, 5, 30}

Answer 1

Answer: The best measure for the central tendency is the median: 4.5

For this data set:
Mean: (3+3+4+4+4+5+5+5+5+30) : 10 = 6.8
Mode : 5
Median : (4+5) : 2 =4.5
In this case, the mean is not the best way to show central tendency.
The median is less affected by outliers and skewed data.
