What is conditional frequency, and how do you determine which value is the denominator?

also, what does it mean if a scatter plot has no association

In the two-way table, It is used to examine relationships between categorical variables. and the entries in the cells can be relative frequencies, that we known as "Conditional Frequency/distribution"

In order to determine the denominator, we add all the values in given column, and for second column,we add all the numbers in 2nd column, & it would be the denominator for each & every cell in that column.

If Scatter plot has no association, then it would not indicate any trends. It means, progression of number can't be formularized in a specific way, 'cause there is no relation between the numbers

Hope this helps!
