Answer:
The median = 5
The mode = 7
Range = 5
Outliers= None
Step-by-step explanation:
The median is the value of the middle term.
The median is that value which divides the data into two equal halves.
7,7,7,7,7,8,8,5,5,5,6,9,9,10,10,10,10,12
There are 18 terms . So the middle term would be 9th term value= 5
The mode is the value which is repeated the most. = 7
Range is the difference between the highest and lowest value.= 12- 7= 5
The interquartile range, IQR= q3 - q1 where q3= 10 and q1= 7
IQR= 10 −7=3
The inner fences can be found out by
q1−(1.5*IQR) and q3+(1.5*IQR)
=7−(1.5*3) and 10+(1.5*3)
Inner fences: 2.5 and 14.5
The outer fences are q1−(3*IQR) and q3+(3*IQR)
=7−(3*3) and 10+(3*3)
Outer fences: -2 and 19
So if there are any outliers in this data set, they will either be less than -2 or greater than 19. But there are no outliers.
