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
