why the value of outlook in correlation matrix is “？”
Hi @AP,
This is because the value can only be calculated when the attributes are numerical or binominal. Outlook is Nominal, and hence a correlation can't be calculated.
Thanks,

“the value can only be calculated when the attributes are numerical or binominal. Outlook is Nominal, and hence a correlation can't be calculated.”—-why？
The statistical method of calculating correlations doesn't support categories, referred to as nominal in AI Studio.
Hope this helps,
“The statistical method of calculating correlations doesn't support categories”，but “binominal” is a kind of categories
