 Hello and welcome to the session. In this session we will discuss a question which says that given any type of relationship, positive, negative or no relationship in each graph here, this is the first graph which shows average temperature with respect to average annual rainfall. And this is the second graph which shows swimming time from the year 1948 to 1996. And if there is a positive or negative relationship, then describe the meaning in situation. Now let us start with the solution of the given question. Now in the first graph we have given average temperature on vertical axis and average annual rainfall on horizontal axis. And on this stator plot we see that the points will be alert where some points are moving upwards and some are moving downwards. And these points are not following the same trend. They are scattered all over the graph. It shows that there is no relationship between the two variables. So we can write that there exists no relationship between the average temperature, average annual rainfall because the points vary a lot and are scattered all over the graph. Now let us see the second graph. Now in the second graph we have swimming time of winning the 200 meters swimming championship on vertical axis and years on horizontal axis. Now here we can see that all the points are moving in downward direction in the stator plot. And we know that when the points are moving in downward direction then there exists a negative relationship between the two variables. So here there is a negative relationship between years and swimming time. And here we can see that with each passing year the swimming time decreases. So we can write that there exists a negative relationship between the years and swimming time of the year increases, the swimming time of the years decreases. This is the solution of the given question and that's all for this session. Hope you all have enjoyed this session.
