Question

Here is a list of numbers.
32 29
20
30
37
34
33
31
Tanya thinks that to work out the median, she simply needs to find
the middle number. So she says that "37" is the median for this list of numbers.
Tanya's answer is not correct.
a) Describe what is wrong with her method.
b) Work out the median of the numbers in the list.

Answer 1

~ Tanya needs to order the numbers correctly first.

~ 20, 29, 30, 31, 32, 33, 34, 37

~ the median is: 31 +32 / 2 = 31.5

~ b) 31.5

Answer 2

Answer:

Step-by-step explanation:

To figure out the median, you first need to order the numbers from least to greatest.

So the numbers ordered should look like this: 20, 29, 30, 31, 32, 33, 34, 37.

Now you find the median.

There are two numbers in the middle, so you have to add those two numbers and divide the sum by 2.

31+32=63.

63/2=31.5

So the median is actually 31.5
