  1. Task: • Think of 3 questions that you could ask the other students in the class • Question one should give you Qualitative data • Question two should give you Discrete Quantitative data • Question three should give you Continuous Quantitative data • Design a data collection sheet for each question and gather the data. • Keep your data safe. You will need it for future lessons… • You might need: • Ruler or tape measure • Weighing scales Getting to know you… maths@kes

  2. Task: • Use your data from the previous task to: • Calculate an ‘average’ for each set of data. … • Draw a range of graphs and charts to represent your findings. You should include: • Frequency table • Bar chart(s) • Pie Chart(s) • Histogram(s) • Cumulative Frequency graph(s) • Write a report explaining what your graphs and calculations tell you about the group. • Which averages are most useful/ possible/ easiest for each set of data? • Which graphs are most useful/ possible/ easiest for each set of data? • You might need: • Protractor or pie chart scale • Graph Paper Doing Data… maths@kes
