Question

A curious student created a performance profile of his favourite cricketer as R = − x 5 + 6 x 4 − 30 x 3 + 80 x 2 + 70 x + c , where R is the total cumulative runs scored by the cricketer in x matches. He picked three starting values shown in Table A-5.2 and tried to find the value of c . If he uses Sum Squared Error method, then what will be the value of c ?

NO OF MATCHES 1, 2, 3
TOTAL CUMULATIVE SCORE 120, 285, 361

Answer 1

Answer:

Answer

the player with less standard deviation i more consistant ,

Mean runs of A =

x

ˉ

A

=47.9.

Mean runs of B =

x

B

=41.6

we know,

Mean deviation (A)=

∑

A

∴ Mean deviation (A)=34.177

Mean deviation (B)=7.727
