The heights of the plants are: 5, 4, 132, 173, 142, 111, 123 (mm)
(b) You have to select the players for your football team. Which of the following given datasets will help you to take the decision?
Dataset 1. Name of the players

Answer:
:
Each part: 1 Mark
Steps: 1 Mark
(a) Since we have to chooseone plant which acts as the dividing point and there are equal number of plants on either side of this dividing point, we needto findthe median.
On arranging them in an ascending order we get,
4, 5, 111, 123, 132, 142, 173
The middle observation is123 mm.
⇒ The median of the observation is123 mm.
(b)The performance of a football player doesn't depend on his name or nationality. Performance solely depends on stamina and height. So, thedata sets which will help us take abetter decision are height and stamina of the players.
