Visualizing a Normal Distribution Given the following score distributions of students in a mathematical quiz. Sketch the graph of the frequency polygon of each distribution. Use a chart wizard of the MS Excel program to sketch the graphs if a computer is available. Answer the questions that follow. 1. Graph the frequency polygon of the following scores of students in a quiz. Here, there are 5 students who took the quiz. X(Score) F 5 2. Now let us increase the number of students to 14. Observe what will happen to the shape of the graph. X (Score) F HNWAU N 14 3. Let us now further increase the number of students. From the first graph to the third graph, observe the transformation of the figures. X (Score) F N 14 4. For each distribution, compute the three measures of averages: mean, median, and mode. What do you notice? What does this imply? 5. Where did you find these measures on the graph? What generalization can you make
