 Hello and welcome to the session. In this session we are going to discuss the following question and the question says that the following table shows the ages of 12 couples at the time of their wedding. Is it a bivariate data? Identify its population and sample. Now let us start with the solution of this given question. Here we are given the ages of 12 couples. Now in the first row we are given husbands age and in the second row we are given wives age at the time of their wedding. So here we are having two series representing two variables that is husbands age and wives age. So it is a bivariate data. Now this data shows our relationship between the husbands age and wives age at the time of their wedding so that we can draw general conclusion such as if husband is of greater age then wife is also of greater age. So here the population will be all married couples and sample is randomly selected 12 married couples so here our required answer will be yes it is a bivariate data and here the population is all married couples and the sample is given by randomly selected 12 married couples. This completes our session. Hope you enjoyed this session.
