What is the median? 0.8 1.0 2.7 2.8 3.1 13.3
Answers
Answer:
2.75
Step-by-step explanation:
The median is just the middle number in the number set. So, you put the numbers in order (which they already are), and find the middle number. If there are two numbers in the middle (which only happens if there is an even amount of numbers), then you add both of them and divide by 2 (which we must do in this problem).
0.8, 1.0, 2.7, 2.8, 3.1, 13.3
(2.7 + 2.8)/2
(5.5)/2 = 2.75
So, the median is 2.75.
Hopefully this helped, good luck!
Step-by-step explanation:
Arranging the numbers in an ascending order:
0.8 1.0 2.7 2.8 3.1 13.3
Median = (3rd value + 4th value) / 2
[tex] = \frac{2.7 + 2.8}{2} \\ = \frac{5.5}{2} \\ = 2.75[/tex]
