Feb 16, 2021 · Solution. Since there are 31 data values, an odd number, the median will be the middle number, the 16 th data value (\frac {31} {2} = 15.5\), round up to 16, leaving 15 values below and 15 above). The 16 th data value is 20, so the median number of touchdown passes in the 2000 season was 20 passes.
