Question

155,160,145.149.150.147.132.144,148 Find the Median and Mode of this data​

Answer 1

Answer:

Total No. of students (N) = 400

2

N

=200

Median Class =165.5−168.5 [having nearest value >N/2]

Median =l+[

f

N/2−cf

]h

l = Lower limit of median class

cf = Cumulative frequency of class preceding median class

f = frequency of median class

h = height of class

Median =165.5+[

136

200−132

]3

=165.5+[

=165.5+1.5

Median =167cm

Answer 2

Answer:

1) median = 148

2) mode = 1

Step-by-step explanation:

1) to find the median first we will first make it in ascending order

  132<144<145<147<148<149<150<155<160  

so the median is 148

2) as mode means the number appearing most often but here all the numbers are occurring once  so mode here is 1

I hope this will help you
