Question

14 is deleted from the data 12,14,15,16,17,18,19,20,then the median increase by

Answer 1

Answer:

The median is 17 if 14 is removed from the data and the median increases by 0.5

Step-by-step explanation:

median with 14 in set

12,14,15,16,17,18,19,20

to find the median with 14 cross 1 number on each side until you come to 2 numbers

you do that because there's an even amount of numbers (8 numbers in set)

you cross the numbers in this order 12,20,14,19,15,18

then you come with 16,17

what's the middle of 16 and 17

well, 16.5 (you can find 16.5 by adding 16 plus 17 and dividing by 2)

median without 14 in set

12,15,16,17,18,19,20

there an odd amount of numbers(7 numbers in set)

you cross one number from each side until your left with one number

12,20,15,19,16,18

your left with 17

so 17 is your median

17 minus 16.5 is 0.5

so, your median increases by 0.5 without 14 in the data

hope this helps
