PHICAL REPRESENTATION OF DATA​

Answer 1

Answer:

range=largest number-smallest number

mean=sum of all the numbers/total number of numbers

(13)median=24

(14)median=20.5

(15)median=38

mode=number with the largest frequency

median=write all numbers in ascending or descending order and cut the number from the two ends

Answer 2

Step-by-step explanation:

(13)median = 24

(14)median = 20.5

(15)median = 30
