Question 1 1.1 What type(s) of data are best for using the following? 1.1.1 A stem-and-leaf plot (2) 1.1.2 A bar chart (2) 1.1.3 Pie chart (2) 1.1.4 Scatter plot (2) 1.1.5 Line graph (2) 1.1.6 A histogram (1) 1.1.7 Box-and-whisker plot (1) 1.2 How is the bar graph better than the pictograph? (4) 1.3 When should we make use of scatter plot graphs? (1) 1.4 In what circumstances are pie charts and bar charts appropriate to be used? (4) 1.5 What makes stem and leaf plots preferable to histograms? (4) [25] Question 2 2.1 The Curriculum and Assessment Policy Statement (CAPS) requires Grade 4 learners to “collect data using tally marks and a table for recording”. 4 2.1.1 How would you introduce the concept of tally marks and a table for recording to Grade 4 learners? Use sports balls as an example. In a Grade 4 classroom of 30 learners, there are 10 learners whose favourite sport is soccer, 6 learners like basketball, 5 like volleyball and 9 like baseball. (5) 2.2 In a class investigation, the heights of Grade 8 learners were measured and converted the measurements to the nearest centimetre. The measurements are as follows: 145 152 146 153 146 154 147 155 148 156 2.2.1 Would you classify this data as quantitative or qualitative? Explain your answer. (2) 2.2.2 Is the data discrete or continuous? Explain your answer. (1) 2.2.3 Organise the data in an ordered stem-and-leaf plot. (6) 2.2.4 Analyse the data you organised in 2.2.3 by writing three statements. (3) 2.2.5 You want to introduce the concept of intervals to the Grade 8 learners. How would you explain the term “interval” using the ordered stem-and-leaf plot you plotted in 2.2.3 as an example? (3) 2.2.6 Using the class intervals of 130≤x140, 140≤x150, 150≤x160, and so on, construct a frequency table to represent the Grade 8 learners’ heights. Your frequency table must include a cumulative relative frequency percentage column. (6) 2.2.6.1 What is the percentage of learners with a height less than 140 cm? (1) 2.2.6.2 What is the percentage of learners with a height of more than 139 cm? (1) 2.2.7 Using the class intervals of 130≤x140, 140≤x150, 150≤x160, and so on, and the frequency count in 2.2.6, construct a histogram to represent the Grade 8 learners’
