Question

find the meadian and the mode of the following data
7 9 12 13 7 12 7 12 15 7 24 18 7
find the meadian and mode of the following data
6 9 12 15 9 3 6 9 12 6 10 3 6 15 6
in a mathematics test given to 15 students the following marks (out of 100) are recorded
41 39 48 52 46 62 54 40 96 52 98 40 42 52 60
find the mean , meadian and mode of the above data

draw a frequency table for the following data
c i cf
111 - 120 6
121 - 130 11
131 - 140 16
141 - 150 20
151 -160 27
161 - 170 36
171 - 180 42
181 - 190 45
191 - 200 50

form the cumulative frequency table less than series from the following data
class interval frequency
0 - 10 3
10 - 20 12
20 - 30 36
30 - 40 76
40 - 50 97
50 - 60 85
60 - 70 39
70 - 80 12
80 - 90 12
90 - 100 6



answer as fast as possible pls be quick

Answer 1

1. median =( n+1/2)th term
->(14/2) term
= 7th term
= 7.
mode= 7

2.median = (n+1/2) th term
= (16/2)th term
= 8th term
= 9
mode=6

3.mean = sum of observations/ no.of observations
= 822/15
=54.8
median = (n+1/2) th term
=(16/2)th term
= 8th term
=40
mode =52
