To identify the outlier in a data set and determine the effect of its removal on the mean, you'll need the specific data points from the set.

An outlier is typically a value that is significantly different from the rest of the data points—either much higher or much lower than the other values.

Once you identify the outlier:

1. **Remove the outlier from the data set**.
2. **Calculate the new mean** (sum of remaining values divided by the number of remaining values).
3. **Compare the new mean with the original mean**.

- If the outlier was high and you remove it, the mean will decrease.
- If the outlier was low and you remove it, the mean will increase.

If you provide the specific data set, I can help you identify the outlier and determine the effect on the mean.
