Question

Please can somebody work out the mean? I'm struggling! <3

Answer 1

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
