A researcher decides to construct a confidence interval for a population median because of very skewed sample data and it is suspected that the population data is also very skewed. Which of the following methods can the researcher use to construct the confidence interval for the population median
a. percentile method only
b. formula method only
c. either the percentile method or the formula method
d. neither the percentile method nor the formula method since a confidence interval for a median can never be constructed

C -

either the percentile method or the formula method 

Step-by-step explanation:

It is possible to get a confidence interval for a sample median, the interpretation of which is directly comparable to that for the mean. However, because of the lack of distributional assumptions, it may not be possible to obtain an exact 95% confidence interval for the median.

we can also use the percentile method to construct a confidence interval. Using this method, the 95% confidence interval is the range of points that cover the middle 95% of sampling distribution

median is the value separating the higher half of a data sample, a population or probablity distribution from the lower half.

step-by-step explanation:

say you have 3,8,7,3,1,9,8 order them from lowest to highest

if orderd it would be 1,3,3,7,8,8,9 now you take away from the lowest and the highest until you end up in the middle.

so you would remove the 1 and 9 leaving you with 5 digits remaining

when you've reached the middle that would be your answer so in this case the answer is 7

if there were two numbers left say 7 and 5 you'd and them together so 12 then divide by 2 witch would equal 6 so the answer would be 6

good luck on that project hoped i you at all
