The median of Y in the following data is .............
\[ \begin{array}{|c|c|c|c|c|c|c|} \hline \text{Serial number} & 1 & 2 & 3 & 4 & 5 & 6 \\ \hline Y & 22 & 12 & 10 & 14 & 16 & 20 \\ \hline \end{array} \]
| Serial number | 1 | 2 | 3 | 4 | 5 | 6 |
|---|---|---|---|---|---|---|
| Y | 22 | 12 | 10 | 14 | 16 | 20 |
To find the median of the values of Y, we first need to arrange the data in ascending order. The given values are 22, 12, 10, 14, 16, and 20.
Sorting these yields: 10, 12, 14, 16, 20, and 22.
The median is the middle value of a data set. Since there are 6 numbers, the median will be the average of the 3rd and 4th values.
Here, the 3rd and 4th values are 14 and 16. The median is calculated as:
\(\text{Median} = \frac{14 + 16}{2} = \frac{30}{2} = 15\)
