The marks obtained by 10 students in a Statistics test are 24,47,18,32,19,15,21,35,50 and 41. What is the mean deviation of the largest five observations?

Step-by-step solution

15,18,19,21,24,32,35,41,47,50 Largest 5 observations are 32,35,41,47,50 aligned Mean & = = 32+35+41+47+50 5 & = 205 5 =41 aligned Mean deviation = |x_i- | n aligned & = |32-41|+|35-41|+|41-41|+|47-41|+|50-41| 5 & = 9+6+0+6+9 5 = 30 5 =6 aligned
