Wecan use boxplot and see if some points are present outside the box then it is most likely due to anomaly.
We can also find mean and standard deviation of the data. If the data is normally distributed, then the data must lie between three standard deviation around the mean ( mean +- 3 * std dev). The data outside it can be considered as anomaly
