Describe what you learned about your classs methods of transportation to school. Jada drank 12 ounces of water from her bottle. Since the data range is from 132 to 148, it is convenient to have a class of width 2 since that will give us 9 intervals. Question: The following table gives the lifetime of 400 neon lamps. Comment on the center and spread of the data, as well as the shape and features. We welcome your feedback, comments and questions about this site or page. X-axis: The intervals under which the measurement falls is shown in the X-axis intervals. Histogram B has two clusters. It is required to make a note that the term normal explains the specific distribution for a process. Assessing Normality: Histograms vs. Normal Probability Plots The histogram was invented by Karl Pearson, an English mathematician. Draw rectangles with bases as class intervals and corresponding frequencies as heights. Sort them into two pilesone for histograms that are approximately symmetrical, and another for those that are not. For example, a boundary such as 100. The bimodal distribution looks like the back of a two-humped camel. Conversely, if a histogram has a "tail" on the right side of the plot, it is said to be positively skewed. Figure \(\PageIndex{4}\): Two histograms, labeled A and B where the horizontal axis has the numbers 10 through 30, in increments of 2, indicated and on the vertical axis, the numbers 0 through 6 .
