Concepts: How to organize data Sample size Types of Data: Quantitative vs Qualitative Probabilities Work for the week: Discussion: Define and provide examples for the statistical measures Complete the following probabilities Use this table to calculate this probability Event B Present Cardiac Disease Event A Depression Present A Depression Not Present A' 7 total Absent (B') Total 14 23 37 Present (B) 12 16 18 19 1. Calculate the P (Depression Present | Cardiac Disease Present) Formula for 1 P (A and B)/P (B) 2. Calculate the P (Depression Present | No Cardiac Disease Present) Formula for 2 P (A and B')/P (B')

Explanation / Answer

Probability (depression present A | Cardiac disease present B ) : P(A&B) / P(B) = 12/19 [ P(A&B) means who have both depression and cardiac disease and P(B) means who have cardiac disease) Probability (depression Present A | No cardiac disease present B`): P(A&B`)/P(B`) = 2/18 [ P(A&B’) means who have depression but not cardiac disease, P(B`) means who doesn’t have cardiac disease)
