Calculate coefficient of mean deviation from median for the following data:
100,150,200,250,360,490,500,600,671
Show answer & explanation
Correct answer: A
Explanation
Statistics given:
100 , 150 , 200 , 250 , 360 , 490 , 500 , 600 , 671
Median = 360
Σ|x − 360| = 260 + 210 + 160 + 110 + 0 + 130 + 140 + 240 +31= 1561
Mean deviation from median = 1561/9= 173.44
Median to median deviation coefficient = 173.44/360
= 0.48
