Answer:

2/ Calculate from the following

• ࿐ i) Median

• ࿐ ii) Mode

• i) Median

• ii) Mode

• Additional Information-

Media

Value of the middlemost observation.

• If n(number of observations) is odd, Median =[(n+1)/2]th observation.

• If n is even, the Median is the mean or average of (n/2)th and [(n+1)/2]th observation.

Mode

• The most frequently occurring observation is called the mode.

• The class interval with the highest frequency is the modal class

i) Median

arranging the given data in ascending order

1,2, 2, 3, 4, 4, 5

..n=7(odd)

so median

n+1) th

(7 + 1) th

2

8

4

median

ii) Mode

here 2 and 4

th

= 3

occurs

most frequently

.. so mode 2 and 4

all WifE
