Answer:
mean = 4.57, median = 5 , mode = 5, range =7 ,
five number summary: Minimum value= 1 , First Quartile = 4, Median = 5
Third Quartile = 6, Maximum value = 8
Step-by-step explanation:
First arrange the data in ascending order.
1,2,2,4,4,4,5,5,5,5,6,6,7,8
Mean = sum of all numbers / total numbers
= 1+2+2+4+4+4+5+5+5+5+6+6+7+8 / 14
= 64 / 14
= 4.57
Median:
Since the given data is even number so, we can find median by taking mean of 2 middle numbers.
so the middle numbers are 7th and 8th data i.e, 5 and 5
Median =(5+5)/2
= 5
Mode:
The most repetitive number in the data set is mode
So Mode = 5
Range:
Range can be found by subtracting smallest number from largest number in the data set.
Smallest number = 1, Largest number = 8
Range= Largest number - Smallest number
= 8-1 = 7
Five no Summary
Minimum value= 1
First Quartile ( 25 % mark )= 4
Median = 5
Third Quartile (75 % mark) = 6
Maximum value = 8
First quartile can be found by : consider the data on left of the median and find median among them
Third quartile can be found by: consider the data on right of the median and find median among them

. We have a diameter for the semicircle, so let's use the diameter formula. 
which is either 
or C = 5.338 if we multiply pi in as 3.14. BUT this is only half a circle, so we only have half that distance around the outside. Therefore, the circumference of half this circle is 2.669 cm. But we need to add the 24 mm in. 24 mm in centimeters is 2.4 cm. So 2.669 + 2.4 = 5.069
