Question

2. Find the median and mode of the following observation
18, 14, 20, 12, 20, 15, 20, 16, 17​

Answer 1

Answer:

12,14,15,16,17,18,20,20,20

Median=17

Mode=

12=1

14=1

15=1

16=1

17=1

18=1

20=3

So the mode is 20

Step-by-step explanation:

For both median and mode you should first take number in ascending order(small to big)

Then, for median you should choose the number in between the number

And for mode you should take the no which has miximium the maximum numbers in table when you count

Okay,

If the median has 2 number in the middle, you should take the mean of the both

Mean=sum of observation

No of observation

In mode if there is two number you can take both as the mode
