Hello Turquoise R2D2!
Thank you for asking us your question!
The median of a distribution is the value in the middle position of an ordered distribution. If the number of values in a distribution is odd, the median is the number at the position \( \frac{n+1}{2} \), where n represents the number of values in the distribution.
If the number of values in a distribution is even, the median corresponds to the mean of the two middle values.
The range is the difference between the highest value and the lowest value of a distribution.
Feel free to reach out if you have any other question!
