In the aggregated dataset, create a statistics worksheet containing a card that displays the Spearman correlation matrix of the seven descriptive columns.

Can anyone tell me what is the Spearman correlation matrix  ?

Hi @Cheyenne ,

Statistics tab can be accessed from the dataset to create a correlation matrix. Please see :
