6. Four histograms are displayed below. These histograms are labelled (on the right-hand side), in order from top to bottom, Histogram A, Histogram B, Histogram C and Histogram D respectively. When answering this question, you should refer to these histograms. Note that all four histograms share the same z-axis, shown at the bottom of the graph. 30 - 20 - Histogram 10- 0- 100- 75- 50 Histograme 25 0 Frequency 80- 60- 40- Histogram 20- 0- 40 - HistogramD 20- -80 -60 -40 -20 0 40 60 80 100 120 20 Values • In random order, the averages of the four sets of data displayed in histograms A B C and D are: 10, 0, 25, 40. , • Similarly and again in a random order, the standard deviations of the four sets of data displayed in histograms A B C and D are: 15, 35, 20 and 10. Your task is to study the histograms shown above, and then to match the correct average value and standard deviation value to each histogram. Each average and standard deviation belongs to just one histogram. When you are confident with your answers, complete the section below. Histogram A: average = Histogram B: average = Histogram C: average = Histogram D: average = .... standard deviation = standard deviation = standard deviation = standard deviation =....
