Should I use the modified Z-score formulation to normalize my data
.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ height:90px;width:728px;box-sizing:border-box;
}
Usually, min max normalization or z-score normalization is used for machine learning. However, they are not robust to outliers. And I did not remove "outliers" in my data because the data is very high dimensional and in the multivariate case, it may not be outliers.
So I was wondering if I can use the modified Z-score method to normalize my data as follows:
If I can't why, why not? Thanks in advance.

Not a programming question, better suited for Cross Validated.
