Question

At noon each day, Mark took temperature readings: 13, 15, 25, 17, 19, 20, and 33 degrees. Find the median of the temperatures. If needed, round your answer to the nearest tenth.

A. 13
B. 23.5
C. 19
D. 33

Answer 1

19

Explanation:

for the median you need to put all the temperatures in order from least to greatest, then find the one in the middle of those.

Answer 2

Answer : The correct option is, (C) 19

Step-by-step explanation :

Median : It is the middle term that is sorted by the list of numbers. It is determine by placing the numbers in increasing order.

For odd observations the formula will be:
`(n+1)/(2)`

For even observations the formula will be:
`(n)/(2)+1^(th)\text{ term}`

As we are given that the set of data:

13, 15, 25, 17, 19, 20, 33

First we have to placing the numbers in increasing order.

13, 15, 17, 19, 20, 25, 33

Now we have to determine the median.

For odd data:

`(n+1)/(2)`

n = 7

`\Rightarrow (7+1)/(2)=(8)/(2)=4`

`4^(th)\text{ term}`

The number at 4th position is, 19

Thus, the median of the given set of data of values is, 19
