Question 1. Find the median of the following data:
(i) 3, 1, 5, 6, 3, 4, 5
(ii) 3, 1, 5, 6, 3, 4, 5, 6
Answer:
(i) Arrange the data in ascending order
We get, 1, 3, 3, 4, 5, 5, 6
∴ Median = (n+1/2) th term
= (7+1/2) th = 4th term
(ii) After arranging data, we get
1, 3, 3, 4, 5, 5, 6, 6
∴ Median = (4+5/2) = 9/2
= 4.5
Question 2. Calculate the mean, the median and the mode of the numbers :
1, 3, 2, 6, 2, 3, 1, 3
Answer:
(a) Mean = 1 + 3 + 2 + 6 + 2 + 3 + 1 + 3/8
= 21/8 = 2.625
Hence mean = 2.625
(b) Arranging the given data in ascending order, we get
1, 1, 2, 2, 3, 3, 3,6
Total number of observations (items) = 8 (even).
There are two middle items : – 2 and 3.
Their average = (2+3)/2 = 5/2 = 2.5
Hence the median of the given numbers = 2.5.
(c) In the given numbers,
3 is repeated more number of time than any other number.
∴ Mode = 3.
Question 3. Calculate the mean, the median and the mode of the following numbers :
3, 7, 2, 5, 3, 4, 1, 5, 3, 6
Answer
(a) Mean = 3 + 7 + 2 + 5 + 3 + 4 + 1 + 5 + 3 + 6/10
= 39/10
= 3.9
Hence the mean = 3.9
(b) Arranging the given data in ascending order, we get,
1, 2, 3, 3, 3, 4, 5, 5, 6, 7
Total numbers of observations (items) = 10 (even)
There are two middle items – 3 and 4
Their average = (3 + 4)/2 = 7/2
= 3.5
Hence the median of the given numbers = 3.5
(c) In the given numbers 3 is repeated more than any other number
∴ Mode = 3
