$= \frac{9}{2}$
$= 4.5$

Answer 2

The median of factors of 18​ is 4.5.

Factors of 18 are 1, 2, 3, 6, 9 and 18

Total number of observations = 6

Since the number of  observations is 6, which is even, the median is given by:

Median =  $\frac{1}{2} [(\frac{n}{2})^{th} term + (\frac{n}{2} + 1 )^{th} term ]$

             =  $\frac{1}{2} [(\frac{6}{2})^{th} term + (\frac{6}{2} + 1 )^{th} term ]$

             =  $\frac{1}{2} [3^{rd} term + 4 ^{th} term ]$

             = $\frac{1}{2} [3 + 6]$

             = 4.5

• The middle value of a dataset displayed in ascending order is determined statistically by the median (i.e., from smallest to largest value).
• The metric separates the dataset's lower and upper halves.
• The median is a measurement of central tendency together with mean and mode.
