Question

With these numbers I have to find the median. Please help mee!!

Answer 1

The median is 12.6.

Put all numbers in order from least to greatest.
$11.9 \: \: 12 \: \: 12.3 \: \: 12.4 \: \: 12.4 \: \: 12.5 \: \: 12.7 \: \: 12.8 \: \: 12.9 \: \: 13.1 \: \: 13.2 \: \: 13.8$
Then cross numbers out, 1st on one end and 1st on the opposite end, so on and so forth. Do this until you get to a number in the middle that is singled out, or until you have 2 numbers singled out in the middle.

In this case you should have 2 numbers, 12.5 and 12.7. Take the average of those 2 numbers.

$12.5 + 12.7 = 25.2$
$25.2 \div 2 = 12.6$
12.6 is your median. Hope I helped!!!

Answer 2

Write them in order from least to greatest,
11.9, 12.0, 12.3, 12.4, 12.4, 12.5, 12.7,12.8, 12.9, 13.1, 13.2, 13.8
then eliminate one from each side until you find the middle one,
12.5, 12.7
you have two middle, so you find the middle number in between them.

12.6 is the median.
