Answer:
A
Explanation:
PRECISION AND ACCURACY ARE TERMS THAT ARE USED TO INDICATE THE QUALITY OF A GIVEN SET OF STATISTICAL OBSERVATIONS.
WHILE PRECISION TALKS ABOUT THE LEVEL OF AGREEMENT AMONGST THE SAME SET OF DATA OBSERVATIONS, ACCURACY TALKS ABOUT HOW FAR OR HOW CLOSE THE TRUE VALUE IS TO THE CALCULATED VALUE. TAKING AN AVERAGE OF ALL THE VALUES, IT STANDS AT 4.735 WHICH IS QUITE CLOSE TO THE TRUE VALUE OF 4.75
NOW, LOOKING AT THE SPREAD OF THE VALUES IN THE OBSERVATION, WE CAN SEE THAT THESE VALUES ARE QUITE NOT CLOSE TO EACH OTHER. HENCE, WE CAN CONCLUDE THAT ALTHOUGH HIS OBSERVATIONS ARE QUITE QUITE ACCURATE BASED ON THE OVERALL AVERAGE, WE CAN CONFIDENTLY POSIT THAT HIS VALUES HAVE A LOW LEVEL OF PRECISION
