of water is found to have
values 1.2, 1.6, 1.4 and
1.8. Calculate the mean
absolute Error
a) 0.8 b) 0.2 c) 0.5 d) 0.05​

Answer 1

Answer:

it's b) 0.2

please mark it brainlist

Answer 2

Answer:

a=a1+a2+a3+a4/4

=1.2+1.6+1.4+1.8/4

=3/2

absolute error A1=|a-a1|

=3/2-1.2=0.3

A2=|a-a2|

=3/2-1.6=0.1

A3=|a-a3|

=3/2-1.4=0.1

A4=|a-a4|

=3/2-1.8=0.3

MAE=0.2
