Question

find mean
and range for the given data
2,4,6,7,974, 6, 8, 10, 7, 14​

Answer 1

mean= sum of observations/no. of observations

= 2+4+6+7+9+7+4+6+8+10+7+14/12

= 70/12

= 5.83

range= highest value- lowest value

= 14-2

= 12

Answer 2

First arrange the numbers in ascending order

2, 4, 6, 6, 7, 7, 8, 10, 14 , 974

Mean = 2+4+6+6+7+7+8+10+14+974/10

= 1038/10 = 103.8

Range = Highest observation - lowest observation

= 974 - 2

= 972
