Question

malala conducted a poll to determine how many twitter followers her friends have. the list below shows the results of the poll. calculate the median number of twitter followers. number of twitter followers 201 199 175 116 followers

Explanation:

Step1: Sort the data

Sort the number of followers in ascending order: \(116\), \(175\), \(199\), \(201\)

Step2: Calculate the median

Since there are \(n = 4\) (even number of data points), the median is the average of the \(\frac{n}{2}\) -th and \((\frac{n}{2}+ 1)\) -th values.
\(\frac{n}{2}=\frac{4}{2}=2\), \(\frac{n}{2}+1=\frac{4}{2}+1 = 3\)
Median \(=\frac{175 + 199}{2}=\frac{374}{2}=187\)

Answer:

\(187\)
