 Hello and welcome to the session. In this session we are going to discuss the following question and the question says that identify whether the relationship has correlation with causation or without causation. The first statement is schools that have more teachers usually have more lunch breaks and the second statement given to us is the older the car the less is its worth. Let us start with the solution of the given question. In the first part we are given schools that have more teachers usually have more lunch breaks. The sentence shows a positive correlation between the number of teachers in the school and the number of lunch breaks in the school but it is correlation without causation because number of teachers have nothing to do with the number of lunch breaks. There may be third variable say long timings of the school which affects both the variables that is number of teachers and number of lunch breaks. Thus it is a positive correlation without causation which is the required answer to the first part of the question. Now the second statement says the older the car the less is its worth. We can see that there is negative correlation between the value of car and time. It is correlation with causation because we know that with time the value of car depreciates thus time causes the worth of car to depreciate hence it is negative correlation with causation which is the required answer to the second part of the question. This completes our session hope you enjoyed this session.
