Step-by-step explanation:
a) Mean=
Total no. of observations
sum of the number
⇒ Mean=
40
2+3+4+3+5+5+6+7+8+9+6+6+5+3+13+7+8+8+2+9+11+7+8+4+5+45+48+60+42+53+47+51+54+49+48+47+53+48+44+46
⇒ Mean=
40
119+770
,
40
889
=22.2
∴ Mean=22.2
b) To arrange data in ascending order
Median : 2,2,3,3,3,4,4,5,5,5,5,6,6,6,7,7,7,8,8,8,8,9,9,11,13,42,44,45,46,47,48,48,49,51,53,53,54,60.
Median =
2
8+8
=
12
6
=8
c)
Mode :- The only number which appears multiple times
Mode =2,3,4,5,6,7,8,9,48,53
d) Range: The subtract the smallest number from the largest number
=60−2=58
∴ Range =58

Answer:
1,2,4,5,5,7,8,9,11,12 =64
Mean is 64/10=6.4
1/2[(n/2)+(n+1/2)]
5th value + 6th value
5+7=12
12/2
6
median is 6
