The table shows the distribution of the distance (in km) covered by 40 hunters while hunting.

Distance (km) 3 4 5 6 7 8
Frequency 5 4 xx 9 2x2x 1

Find the mode of the distribution.

Worked solution (try it first)
  1. Find xx first: 3x+19=403x + 19 = 40, so x=7x = 7 and 2x=142x = 14.
  2. The frequencies are 5, 4, 7, 9, 14 and 1.
  3. The largest is 14, at 7 km.
  4. So the mode is 7 km, option C.
