2. (a)  If you have not yet done so, calculate how many rhinos
                          were killed in total every year from 2010 to 2014.

                      (b) Calculate the number of rhinos killed in each of the
                          provinces between 2010 and 2014.

                      (c) Do you think the problem of rhino poaching is getting
                          worse or better? Explain why you say so.


                  Reading data in bar graphs



                  We draw graphs to help us see quickly how to compare data. Bar
                  graphs are not as accurate as data in tables, so we have to estimate
                  carefully when we read graphs.


                              1 400
                            number of rhinos killed  1 200
                              1 000
                                800
                                600
                                400
                                200
                                  0
                                      2010 2011 2012 2013 2014
                                                         Years


                  1. (a)  Give the graph a heading. Write the heading in your book.
                          Your heading must tell what the graph is about.
                      (b) Estimate the number of rhinos killed each year.

                      (c) How many rhinos were killed altogether from 2010 to 2014?

                      (d) How many more rhinos were killed in 2014 than in 2013?
                      (e) If you look at the graph, how many rhino killings do you
                          expect in 2015? Explain why you say so.

                  2. Write a short paragraph to tell the story about rhino poaching
                      in South Africa between 2010 and 2014.
