Which of the following is true for a median? Medians are affected by outliers. Medians can be calculated no matter how the data
Lady bird [3.3K]

Answer:

Option D) is true about median    

Step-by-step explanation:

We are given the following information in the question:

Median:

  • The median is the middle number or the center of the data when the data is sorted in either ascending or descending order.
  • The median is not affected by the presence of any outliers since the data is sorted.

Median:\\\text{If n is odd, then}\\\\Median = \displaystyle\frac{n+1}{2}th ~term \\\\\text{If n is even, then}\\\\Median = \displaystyle\frac{\frac{n}{2}th~term + (\frac{n}{2}+1)th~term}{2}

Option A) Medians are not affected by the outliers

Option B) Medians can only be calculated when the data is sorted.

Option C) This is a false statement about the medians.

Option D) True

When there are even number of observations, the median is the mean of the two middle numbers.
