Question

Given the series:
3,5, 2, 7, 6, 4, 9, 3, 5, 2, 7, 6, 4, 9, 1
Calculate
The mode, median and mean
The average deviation, variance and standard deviation​

Answer 1

Step-by-step explanation:

Ascending order :1,2,2,3,3,4,4,5,5,6,6,7,7,9,9.

Mean=sum of all observation /total no. of observation

=1+2+2+3+3+4+4+5+5+6+6+7+7+9+9/15

=73/15

=4.86

Mode =Maximum frequency

= No number because every no. repeated only leave 1

here, 15 it is odd

Median= (n/2+1) term

=(15/2+1)term

=16/2th term

=8th term

=5
