Respuesta :

The numbers are a bit blurry so I can't determine the numeric standard deviation for each set. However, we can see that the histogram on the left has an outlier, which will increase the standard deviation compared to the data set that doesn't have an outlier. Therefore it is likely data set U has a larger standard deviation.
