Question

112. Find mean, mode & median of<br />(75,62, 88, 55, 90, 95, 85, 69, 62, 78, 90,95,90,95,80,71,44,57,68,90​

Answer 1

Answer:

Mean=26.55

Median = 10th observation =78

= 11th observation =80

Mode=90

Step-by-step explanation:

Mean: sum of all observations /Number of observations

75+62+88+55+90+95+85+69+62+78+90+95+90+95+80+71+44+57+68+90/20

=531/20

=26.55

Median=44,55,57,62,62,68,69,71,75,78,80,85,88,90,90,90,90,95,95,95

=n/2th observation and n/2+1th observation

=20/2 th observation and 20/2+1th observation

=10th observation and 10+1th observation

=10th observation and 11th observation

=10th observation=78

=11th observation =80

Mode=The most frequently repeated number

=90
