Given data

 S.No. Value S.No. Value 1. 81 9. 95 2. 81 10. 96 3. 86 11. 97 4. 87 12. 98 5. 89 13. 98 6. 92 14. 101 7. 93 15. 101 8. 94 16. 106

Step 1 of 5</p>

Median=( )th value

=( )th value

=(8.5)th value

=Average of 8th And 9th value

=94.5

Step 2 of 5</p>

Largest value=106

Smallest value=81

Range=Largest value - Smallest value

=106 -81

=25

Step 3 of 5</p>

First Quartile (Q1 ) =( )th  Value

= ( )th  Value

=4.25th  value

=4th  value+0.25(5th value- 4th  value)

=87+0.25(89-87)  =88.5
