Frequency and Histograms 1) The frequency table below shows the ages of people attending a high school play. Age Frequency 0-19 47 20-39 43 40-59 31 60-79 8 a) Make a Histogram to display the data histogram with age groups on the xaxis and frequency on the yaxis b) Make a cumulative frequency histogram showing the number of people attending who were less than 20, 40, 60, or 80 years old. cumulative frequency histogram with age groups on the xaxis and cumulative frequency on the yaxis 2) The winning distances for the girls’ discus throw at an annual track meet are shown below. Make a histogram to display the winning distances. Make sure to create your own bin or interval range. Year Distance 1999 119 2000 124 2001 126 2002 129 2003 130 2004 130 2005 133 2006 135 2007 136 2008 137 2009 138 2010 140 histogram with distance ranges on the xaxis and frequency on the yaxis 3) The data set below shows the math scores received on the second semester final. Range: 5-7 bins Scores: 33, 54, 71, 88, 98, 37, 59, 65, 65, 46, 60, 89, 90, 49, 64, 65, 70, 70, 84, 86, 90, 55, 67, 78, 92 a) Make a frequency table of the data. Math Scores Frequency 33-46 3 47-60 6 61-74 8 75-88 9 89-102 6 Total 32 b) Make a histogram of the frequency. histogram with Math Scores on the xaxis and Frequency on the yaxis c) Make a cumulative frequency table. Math Scores Frequency ≤ 46 3 ≤ 60 3+6=9 ≤ 74 9+8=17 ≤ 88 17+9=26 ≤ 102 26+6=32 d) How many students took the test? What are 3 ways to find the answer? Add up the frequencies Look at the cumulative frequency table Count the number of scores e) In what 10-point letter grade range did the largest number of students score in? 75-88
