Considering that the data has no outliers, the mean of 3.2 inches should be used to describe the center of the data represented in this line plot.

<h3>What measure should be used to describe the center of a data-set?</h3>

It depends if the data-set has outliers or not.

  • If it does not have outliers, the mean should be used.
  • If it has, the median should be used.

The dot plot gives the number of times each measure appears. Since there is no outliers, that is, all values are close, the mean should be used. It is given by:

M = (2 x 1 + 3 x 2 + 2 x 3 + 1 x 5 + 1 x 6 + 1 x 7)/(2 + 3 + 2 + 1 + 1 + 1) = 3.2 inches.

The mean of 3.2 inches should be used to describe the center of the data represented in this line plot.
