"Hello everyone. Welcome to lido homework session today. We are going to solve a problem from the chapter data handling. Today's question is your the use the bar graph to answer the following questions. So they have two sub questions, which is the most popular pet and how many students have a dog as a pet? So to find out which is the most popular pet. We simply have to look at the bar graph. That is the tallest. So the tallest bar in this graph is obviously cat. So that is the most popular pet. So I'm going to write the answer here with that. We have answered the first question for the second question. We are asked how many students have a dog as the better so we can look at the Bar for dogs and we see that it's exactly touching the eight tick mark on the y axis so we know that the number of students who have dogs as pet is eight with that. We have come to the end of this problem. I hope you found this video helpful and fun.
