choose two additional data values for the given data set so that the given data set is true A. the median is 8 4,12,14,10_,_ B.
sergiy2304 [10]
First step in finding the median is ordering the numbers 1. 4,10,12,14. Then you find out the number in the middle.
step 1:  4,10,12,14
step 2: now, take out the first number so  10,12,14
Step 3: now take out the last number so  10,12
step 4: since there are two middle numbers, you average them. If you didn't know already, all you have to do to average them is add the two numbers together then divide them by two so 10+12=22 /2=11
now you want to find two numbers that  if averaged with 11, make 8. so you could do two . final answer is  4,5,5,10,12,14

<span>1. 4,12,14,10,5,5
2.</span> 4,12,14,10,12,10

now mean is just average so what you would do is just add all your numbers up and divide by the amount of numbers you added.
