Step-by-step explanation:
The formulae for median is
N=£f/2 that is the sum of frequency divide by two
Median =Nth term + (N + 1)th term divide by two
first of all do the cumulative frequency which is
2+0=2
2+8=10
10+4=14
14+10=24
24+6=30
therefore N=£f/2
N=30/2
=15
when you use the formulae
it will be 15+(15+1)/2
then check the cumulative frequency the value close to the range of 15 and 16 which is 14
then you trace 14 back to the conceded goals
which is 2
then you add 2+2 and divide by two
which is= 2
therefore the median is 2
Mean
formulae
mean=conceded goals multiply by the frequency/sum of frequency
0*2=0.
1*8=8
2*4=8
3*10=30
4*6=24
total is 70
sum of frequency is 10
according to the formulae 70/10=7
therefore the mean is 7
