Question -
Answer -
Arranging the givendata in an ascending order, we get
= 12, 12, 13, 13, 14,14, 14, 16, 19
Mode,
Mode is the value ofthe variable which occurs most frequently.
Clearly, 14 occursmaximum number of times.
Hence, mode of thegiven data is 14.
Median,
The value of themiddle-most observation is called the median of the data.
Here n = 9, which isodd.
Where, n is the numberof the students.
∴median = value of ½ (9+ 1)th observation.
= ½ (9 + 1)
= ½ (10)
= 10/2
= 5
Then, value of 5th term= 14
Hence, the median is14.
