Our dataset is currently loaded into a homogeneous array of strings, ndarray::Array2<String> . This data type has allowed us to load all our data in from a CSV file without prior knowledge of the suitable data types. However, it now means that we cannot apply pertinent operations depending on the feature. For example, we aren't able to easily determine any central tendencies for the SepealLenghCm column, or convert our units from centimetres to something else. All we can do right now is operate on these values as strings.

Let's see what happens if we try to operate on the data in its current form, e.g. if we want to find the mean average value of each column.
