Question

So I don't know how to do this. I know how to find the median of numbers. But I have a picture it's like a number line with dots on top of the number.

What is the median life expectancy below? What is the range of life expectancy below?

Number line represents years.

Year. How many dots
74. 1
77. 1
78. 2
79. 2
80. 5
81. 2
82. 4

Answer 1

Median is the middle number in a sorted list of numbers.

In this case:

1 ,1 , 2 , 2 , 5 , 2 , 4

Put them in order:

1 , 1 , 2 , 2 , 2 , 4 , 5

Median is 2

The range is the difference between the largest and smallest values.

In this case Range = 5 - 1 = 4

Answer 2

Answer 3
