Answer:
1. the range is 68
2. the iqr is 37.5
3. the mode is 17
4. the mean is 52
5. the median is 44
6. min=7
q1=17
median=39
q3=55
max=62
iqr=38
7. data set a: q1=2 median=4 q3=5 iqr=3
data set b: q1=1 median=5 q3=7 iqr=6
Explanation:
1. in order to find the range you subtract the largest number from the smallest number in this case its 81-13
2. you need to put the numbers from smallest to largest then you find the first quartile and the third quartile in this case it would be q1=(8+12)/2 =10 and q3= (39+56)/2=47.5
then you find the iqr by subtracting q1 from q3 so q3-q1= IQR
3. the mode is the number that shows up the most
4. to find the mean you have to add up all the numbers than divide it by how many numbers there are so all the numbers add up to 260 and you divide that by 5
5. to find the median you need to put the numbers from smallest to largest and the number in the middle is the median
i hope i helped! and for 6 and 7 you just do everything i mentioned above :)
