A researcher conducts a study on the heights of a group of 30 students in a classroom. The recorded heights (in centimeters) are as follows:
150, 152, 153, 155, 155, 156, 158, 160, 161, 162, 162, 163, 164, 165, 165, 166, 167, 168, 170, 172, 173, 175, 175, 176, 180, 182, 183, 185, 187, 190
Using this data, what is the median height of the students?
