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

Answer 1

The median value of the data set on the line plot is 30.

The data values are: 27, 28, 28, 29, 29, 29, 30, 30, 30, 31, 31, 31, 33, 34

Arranging the data set in numerical order: 27, 28, 28, 29, 29, 29, 30, 30, 30, 31, 31, 31, 33, 34

The median value is the middle value when the data set is arranged in numerical order, in this case it is 30.
