Answer 1

The mode is 7 , median is 7 and the range of data is 2.8

Explanation:

Stem leaf diagram :

5 | 7 7 9

6 | 5 6 8 8 9

7 | 0 0 0 2 5 5 7 8

8 | 4 4 5

Key : 5|7 means 5.7 cm

So, Data : 5.7,5.7,5.9,6.5,6.6,6.8,6.8,6.9,7.0,7.0,7.0,7.2,7.5,7.5,7.7,7.8,8.4,8.4,8.5

a)Mode : The most occurring number in the data is the mode

So, 7 is the mode of the data

b)

No. of observations = n = 19

`Median = (n+1)/(2)\text{th term}\\Median = (19+1)/(2) \text{th term}\\Median = 10 \text{th term}\\Median = 7.0`

C)Range = Maximum - Minimum= 8.5 - 5.7 =2.8

Hence The mode is 7 , median is 7 and the range of data is 2.8
