As there do not appear to be any outliers in this data set, the mean can be used to best describe the center of the data.
How to find mean and median of a data?
Mean is the ratio of sum of the observations to the total number of observations.
Median is such a number for the arranged data set(ascending or descending order) such that to its left and to its right belong same number of observations.
Ordered data values: 1, 1, 2, 2, 2, 3, 3, 5, 6, 7
Therefore, the Median = 2.5
The Mean =
[tex]\dfrac{1+ 1+ 2+ 2+ 2+ 3+ 3+ 5+ 6+ 7}{10} \\\\= 3.2[/tex]
