Let's try to calculate positive and negative likelihood ratios

Firstly, lets ensure that you understand where the variables are to be placed in a 2x2 table.

Fill in the empty table below with the correct variables.

(True Positive= TP, False Positive= FP, True Negative=TN, False Negative=FN)

***PLEASE NOTE YOU MUST USE CAPITAL LETTERS IN YOUR ANSWERS*** 

Now that you know where the 4 variables go in the 2x2 table, enter the variables in the correct location for the positive LR equation. Fill in the numerator and denominator for the positive LR with the correct values of TP, FP, TN, FN.

And now do the same for the negative LR equation. Fill in the numerator and denominator for the negative LR with the correct values of TP, FP, TN, FN.
