............

Answer 2

Answer:

median = 7

mode = 3

range = 8

Step-by-step explanation:

Finding the median , mode and range

median is the middle number in a data set.

mode is the number that appears the most in a data set

range is the largest number minus the smallest number in a data set

firstly

arrange the numbers in ascending order

= 3 , 3 , 5 , 7 ,8 , 9, 11

median

since the number of values in the data set is 7

means its an odd data set.

the formula to use for an odd data set is

= (number of values + 1 ) /2

= (7 + 1 ) /2

= 4 th position

3 , 3 , 5 , 7 ,8 , 9, 11

this states that the median is in the 4th position

median  = 7

Mode

the number that appears the most

3 , 3 , 5 , 7 ,8 , 9, 11

the number 3 appears the most

mode  = 3

Range

highest - lowest value

= 11 - 3

range = 8
