To find the median, you organize the given numbers (data), from either a least to greatest order or greatest to least order.
To find the mode of said numbers (data), just see which number is being stated more than once (or twice) compared to the other data.
In your case...
The median is, "19.33".
The mode is, "No mode." (because none of those values are being repeated more than once).
Hope I cleared up any and all issues, have a nice day!
