How Do You Create A Histogram Online?
A histogram is a type of bar chart that represents a frequency distribution in statistical analysis. The height of each bar tells you how many times a certain item was observed in a particular category. For example, you might use a histogram to plot the heights of students, with categories for 4 to 5 feet tall, 5 to 6 feet tall and 7 to 8 feet tall. The height of the bar would represent the relative number of students with heights that fell into each category. Locate an online histogram tool, such as one by the National Council for the Teachers of Mathematics (NCTM), Shodor or Zweigmedia. Enter the data for the histogram in the appropriate box, following the site’s instructions. For example, the NCTM histogram tool requires you to enter your data, one per line. For heights of students, you might enter: 5.2 5.1 5.4 5.3 5.7 5.1 5.6 5.8 6.0 Enter the interval size. You’ll want to play around with this to get a decent graph. For the height data above, you might have categories of “5.0 to 5
