Which value on the number line is the best estimate of the center of the data set?



A line plot with twenty-two data values. Labels are at zero, three, six, nine, and twelve. Tick marks are every one unit. Values appear as x marks above the line. Plot data values are one x mark above one, one x mark above two, two x marks above three, two x marks above four, three x marks above five, four x marks above six, three x marks above seven, three x marks above eight, two x marks above nine, and one x mark above eleven.

Data set:
1, 2, 3, 3, 4, 4, 5, 5, 5, 6, 6, 6, 6, 7, 7, 7, 8, 8, 8, 9, 9, 11

Center of the data set is the median of the data set. Since, the number of data set is even, we need to get the two middle terms, the 11th and 12th term.

11th term = 6
12 term = 6

median = (6+6)/2 = 12/2 = 6

The center of the data set is 6.
