Answer:
The mode is 7 , median is 7 and the range of data is 2.8
Step-by-step 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
[tex]Median = \frac{n+1}{2}\text{th term}\\Median = \frac{19+1}{2} \text{th term}\\Median = 10 \text{th term}\\Median = 7.0[/tex]
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
