Question

find the median of (25,14,28,17,18,14,25,14,17,14​

Answer 1

Answer:

Median = 18

Mode = 14

Step-by-step explanation:

We are given data 14,25,14,28,18,17,18,14,23,22,14,18. We need to calculate median and mode.

First we arrange data in ascending order.

14,14,14,14,17,18,18,18,22,23,25,28

Now we count number of data, n=12

Median: It is middle value of the arranged data.

For median, \frac{n}{2}

term of the data

Median = 18

Mode: It is an element of the data set which appears at most.

Here we can see 14 appears 4 times that is maximum number of times.

Therefore, 14 is mode of the given data.

Mode = 14
